One day this happens: your child asks a question about how the body works. How we breathe, digest food, why our heart beats so often, or why mom has so many freckles. Books will help you answer them - those that tell about the body in a clear, easy and fascinating way. Open them with your little ones or give them to your teen to read.

1. Why?

At the end of the book there are pages for your “whys”: there moms and dads can write down the “pearls” and questions of their kids.

For whom: for children from 3 years old

2. Bones and skeletons

Children will be able not only to read, but also to compare the sizes of bones and body parts. And also look at the amazing illustrations of Steve Jenkins: he works using the collage technique and collects pictures from paper. A book about skeletons can easily become a child’s favorite reading.

For whom: for children from 4 years old

3. Anatomy

An illustrated anatomy atlas that clearly explains how the human body works. The special feature of the book is its carved illustrations. We open the valve and look at what the digestive system or the eye consists of. The illustrations are detailed but not scary. And also anatomically accurate, because the book was checked by physiologist and candidate of biological sciences Olga Sergeeva.

“Anatomy” has a large format and bright design. This book is interesting to read and a pleasure to give as a gift: it will definitely appeal to big and small readers.

All the facts are presented in a fascinating and accessible way: the book will appeal not only to little children, but also to their parents.

For whom: for children from 5 years old

5. How the body works

Children will learn about amazing facts that they encounter every day. What tells us that we are hungry? Why do we feel a sick feeling in the pit of our stomachs when we are very nervous? And who has more genes - the bulb or the person? Interesting and educational.

For whom: for schoolchildren from 10 years old

6. If you want to be healthy

The book contains information on how to harden yourself, do exercises and sit at the computer. And artists Anastasia Balatenysheva and Anastasia Kholodilova drew cute illustrations and a diagram that will help you brush your teeth correctly.

How is a person made? For children, answering this question will not be so easy. And even more so to understand this complex mechanism. But everything in the human body is subject to certain laws.

Body structure

How the body works is a multicellular organism. From a systematic point of view, this is a representative of the embryonic development stage in which the notochord, neural tube and gill slits in the pharynx are formed. As they develop, they transform into the skeleton, spinal cord and brain, and the lungs become respiratory organs. Like all mammals, humans feed their young with milk, have mammary, sweat and sebaceous glands, hair and horny skin formations.

How is a person made? Its body consists of cells that combine into tissues. The combination of the latter, in turn, forms organs. However, each of them individually is not capable of performing complex functions of life processes. Therefore, organs are combined into physiological and functional systems.

Features of animal cells

The cells of the human body have a structure typical of animals. They are eukaryotic because they have a nucleus. This permanent cellular structure contains genetic information contained in DNA molecules. By type of nutrition, humans are heterotrophs. For this reason, its cells are deprived of green plastids of chloroplasts, in which the process of photosynthesis occurs. The main organelles are mitochondria, lysosomes, Golgi complex, endoplasmic reticulum, cytoskeleton and centrioles.

How a person works: the main types of body tissues

Groups of cells that have a unified structure and function are called tissues. There are four types of tissues in the human body:

1. Epithelial - consists of small, tightly adjacent cells. It forms the coverings of the body and internal organs; its special variety is the basis of the glands. It contains virtually no epithelial tissues that perform the function of protection and metabolism with the environment.

2. Connective - is the basis from which human organs are composed. Consists of large cells that are located in a large amount of intercellular substance. Its varieties are bone, cartilage, fat, and blood.

3. Muscular - consists of fibers capable of contraction. Performs the function of moving individual organs and the whole organism in space.

4. Nervous - formed by neurons with numerous processes that transmit various types of information, ensuring the interaction of the body with the outside world.

Human organs and systems: features of organization

Each organ consists of several types of tissues. For example, the heart is formed by muscle tissue surrounded by a connective tissue membrane. But the skin is rightfully considered the largest organ. After all, its total area is up to 2 square meters. Why is skin an organ? Because it consists of several tissues: epithelial and connective.

To understand how a person works, it is necessary to become familiar with the concept of an organ system. Examples of such structures are known to everyone: digestive, circulatory... Each of them is a collection of organs united to perform a single function. Let us consider these structures of the human body in more detail.

Musculoskeletal system

The very first lesson in the anatomy course is devoted to this system. How does the human body work? First of all, it is based on a skeleton. It is represented by several departments. This is the skeleton of the head, torso, girdles and free upper and lower limbs. Unlike other animals, humans tend to walk upright. The ability to move is provided by muscles that are attached to bones by ligaments.

Respiratory and circulatory system

We continue to consider how the human body works. Its existence is impossible without gas exchange. This function is provided by two systems at once. The respiratory system is also represented by the lungs. When you inhale, oxygen from the air enters them. From the pulmonary vesicles this gas enters the smallest capillary vessels. With the blood flow, oxygen flows to every cell of the body. In the opposite direction, carbon dioxide moves, which is also removed from the body through the lungs.

The system is represented by a four-chambered heart and blood vessels: arteries, capillaries and veins. The type of this system in humans is closed, since the blood in his body does not mix with the cavity fluid, but circulates only inside the vessels.

Digestive and excretory system

Human life is impossible without metabolism with the environment. The intake, breakdown and absorption of nutrients is carried out by the digestive system. How does the human body, and specifically this set of organs, work? It is represented by the oral cavity, pharynx, esophagus, stomach, small and large intestines, which open with the anus. This is a through-type digestive system. But the implementation of its functions would be impossible without specialized glands that secrete enzymes that break down complex organic substances into simple ones. These include the salivary glands, pancreas and liver.

It is represented by paired bean-shaped kidneys, ureters, a bladder, and a canal that opens outward. With its help, the body gets rid of excess water, salts and toxic metabolic products.

Features of the structure of the reproductive system

Let's consider how a person works from the point of view of reproductive function. It is a dioecious organism with a developmental type - direct. Both the female and male reproductive systems are represented by glands, ducts and cells. However, they have significant differences. In men, these are the testes, their ducts and mobile small gametes - sperm. These cells are always active and capable of fertilization.

The female reproductive system is represented by paired ovaries, oviducts and immobile, relatively large gametes. For fertilization, they need to move from the gonads to the fallopian tube. This process occurs only during a certain period of the menstrual cycle, which is called ovulation. When gametes fuse, a zygote is formed. It divides and gradually forms a multicellular structure, which will later turn into a fruit. The intrauterine development of the embryo provides reliable protection for the small organism during pregnancy and viability in the first months of life.

Features of the human nervous system

Only man is a biosocial being. This is largely achieved due to the high level of development of the nervous system. It consists of the spinal cord and brain, as well as the nerve fibers that extend from them. A person is born with a certain set of unconditioned reflexes and animal instincts. However, during his life he also develops acquired reactions. How does the human brain work? More complex compared to other chordates. It contains the cerebral cortex and a large number of convolutions, which significantly increase its area. Only humans are characterized by meaningful speech and abstract thinking. He lives in society and is to a certain extent subject to social laws.

Regulation of functions

Naturally, in such a complex system, regulation of functions is necessary. This happens in two ways simultaneously. With the help of the nervous system, the human body receives information about various changes in environmental conditions and reacts to them almost instantly. This is largely accomplished by sensory systems. A person has five of them. These are vision, touch, smell, hearing and the ability to perceive odors. Some scientists identify another one, which is called the “sixth sense”, or intuition. However, no one has yet succeeded in discovering or explaining the structure or mechanism of this system. And the endocrine glands, releasing special substances into the blood - hormones, regulate the processes of growth, development and homeostasis. This concept implies maintaining a constant internal environment.

This is how the human body works. This is a complex system that sequentially unites cells, tissues, organs and their systems. Each of these structures has a high degree of specialization and is coordinated through the nervous and humoral regulatory systems.

Of course, every day I myself explained to them, as well as a book, about the correctness of healthy food, but at that age, clarity is important for children, and the pyramid of food on the first spread was etched in their memory better than any words. Then in our house you could often hear something instructive, like “...this is harmful...” or addressed to my husband, who has a big sweet tooth: “Stop eating sweets”)))

We quickly studied the book and then I started thinking about what interesting things I could come up with next time. My whys bombarded me with questions in two voices every day, and I decided to prepare thoroughly.

The books were bought at different times, some 2.5 years ago. A hit with children was “Little Doctor” from Azbukvarik, in which you had to answer questions after studying the topic by pointing a thermometer in the right place. At the same time, a sound and the phrase “Wrong, think carefully” or “That’s right, smart girl, little doctor” are heard. .The children loved poking so much that they knew all the answers even before studying the topic). The book “The Human Body. My First Encyclopedia” by Machaon is a favorite to read and review, although I don’t like it artistically. There are more beautiful books.

And for myself, I bought a large, heavy “Human Anatomy”, creepy and more than detailed. The book presents computer images of a three-dimensional model of the human body in great detail. The model was 20 years old, and the model is based on 7 thousand photographs of cross sections of male and female bodies, frozen in a hardening agent and cut horizontally into layers of 0.3 mm (!) . Brrr...But this is exactly what is needed for those who lack spatial imagination and have very vague knowledge of anatomy.

Here are some cool books that are still on sale:

2) My body. From crown to toes ()

5) Human anatomy 360°. Illustrated atlas (Labyrinth.ru)

The prices for many books are simply exorbitant, so I advise you to purchase them during promotions.

2. Our classes.

Internal organs and skeleton.

I circled Nastenka and Yulichka on a roll of wallpaper. They left Yulia because... Nastya was spinning and it turned out crooked.

Then I cut out the internal organs and skeleton from thin cardboard. So I had to tinker with them. It could have been done simpler, but I wanted more detail and accuracy, so I took the long route. I glued bubble wrap onto the lungs, which is what equipment is wrapped in, and put all the parts of the skeleton in bags and taped them inside so they wouldn’t move.

Veins and arteries were made from threads. There was only white yarn, so I let the children paint it with gouache in the desired colors. By the way, the lymphatic and nervous systems can be laid out in the same way.

Nastenka liked the skeleton costume. There is a funny song on this topic on YouTube The Skeleton Dance - Super Simple Songs.

But the children feed the skull with medicine)

After completing the topic, I showed the organ I had studied on Jerry’s skeleton from the book “Assemble the Human Body. 3D Puzzle,” and the children laid out the homemade organs like a puzzle on our model. By the way, you can clearly demonstrate real organs to children when you cook in the kitchen, for example, the liver, and even cut it together. And for those with a sweet tooth, you can bake cookies and draw funny skeletons on them with icing.

And here is our pasta skeleton. Children were not attracted to ordinary pasta, but colored pasta was a completely different matter!

I colored the pasta like this: I diluted food coloring in small containers in cold water (I had Wilton for icing), I took a lot, the water turned out cloudy. I threw the pasta into the container and left it for 20 minutes. Then I threw all the pasta in a colander one by one and laid it out on trays previously covered with film. The main thing is not to mix pasta of different colors, but to put each batch separately. I left it to dry for a day. Food coloring is good because the product painted with it is bright and does not stain in your hands.

Teeth.

We studied the mouth and types of teeth, and once again talked about the need to brush teeth. Last year we had to draw a mouth with teeth many times. All the teeth smiled if healthy food was “put” in the mouth, and cried and turned black if harmful food was put in the mouth. And this year the children sculpted teeth for Mr. Nibbler. We learned how to drill holes and make fillings and braces.

But in the photo, Zubastic lost all his teeth because he ate a lot of candy and didn’t brush his teeth)

Hands.

Children, especially Nastya, don’t like it when I smear green paint on their hands. And in a playful way they happily made “cuts”, treated them and covered them with a band-aid.

trimmed nails

painted with varnish

we drew decorations - we are girls)

Brain.

Julia colored the brain caps, and I glued them together.

I signed everything in Russian, in the original in English.

Abstract of the OD “Structure of the human body” for preschoolers with presentation

Software tasks.

1. Give children ideas about the structure of your own body, expand your understanding of your body, its structure.

2. Encourage children to speak up. Strengthen the skill of correct construction and the use of complex sentences.

3. Expand knowledge preschoolers about nutrition, its significance, the relationship between health and nutrition.

4. Cultivate the desire to be beautiful and healthy.

Preliminary work.

Consideration of illustrative material about the body person, posters, diagrams; reading encyclopedic literature, asking riddles; conversations about body structure, about the body, about the benefits of a healthy diet; conducting exercises and didactic games.

Progress of the lesson.

Educator.

High, low, distant, close,

Giants, gnomes, kids,

The weak and the strong,

Blondes, brunettes, brown-haired people,

And all sorts of natives,

And fathers, and mothers, and children -

There is nothing more dear to them in the world.

Everyone seems to be different in appearance, But everyone has arms, and legs, and a mouth, Two ears, two eyes and a nose. But no matter how different we are, we are still similar in our physique. Guys, let's remember once again what parts the body consists of. person.

The child says the words and shows the named part of the body on the diagram "Body person» .

Everyone should have

A very "smart" head.

I believe her as best I can

The head sits on the neck.

Tummy, back, chest,

Together they are called the torso.

I ate all the food, and now

My belly was full.

Don't forget on your walk

Cover your chest from the wind.

Hands - to caress, to work,

Drink water from a mug.

Boys sitting on the hand

Very friendly fingers

Running along the path

Frisky legs.

Stumbled through Genka

And I hurt my knee.

Playback What parts of the body did you not name?

Children. Shoulders, pelvis, hip, foot.

Playback Well done you know well human body structure. Can you find the named part by touch? body?

A game “Find the named part by touch body» .

Children become pairs, one child from the pair has his eyes closed, and he must find the part named by the teacher body. Then the children change places. Okay, you completed this task.

There are four assistants in your service,

Without noticing, you use them jokingly:

Eyes were given to you to see,

And the ears are used to hear,

Tongue in mouth to understand the taste

And the nose is able to distinguish the smell.

A game "Part and Whole"

The whole is the face person(in a circle). Parts - petals (ear, mouth, nose, eye, laid out in the form of a flower.

Now we’ll rest and start playing again.

Physical exercise.

Boys live with merry little fingers.

Mischievous feet walk along the path.

The neck turns its head

Repeat everything after me.

Right, left turn,

Show me your tummy.

Our body has tightened up

And it leaned forward slightly.

Like a birch tree slim

My back became straight.

And now everyone has caught up

And they smiled at each other.

Repeat 2 times.

Playback Know the structure of our body means knowing yourself. The more you learn about yourself, the better. Inside the body contains organs that help person, grow and develop.

Guys, put your hand on your chest like I did. Let's sit quietly and listen to ourselves. Do you feel something knocking inside?

Playback What is it?

Children. This is the heart. The heart is a very important organ.

Children. Right. We cannot see it, but we can hear it if we put our hand to the chest, as we just did.

Playback What does a heart look like?

(the child shows the organ in the diagram - the heart)

Playback Heart person slightly larger than his fist. Clench your fist and we will see who has what heart.

Guys, tell us how the heart works?

Children. The heart works day and night without rest. It moves blood like a pump throughout the body.

Knock-Knock

The heart is beating

Similar,

Like a motor.

If your heart beats like that,

Means, the person is healthy.

Playback Yes, the heart is an important organ.

Now let’s freeze and listen to our body. What else do you feel and hear?

Children. We hear our breathing.

Playback U person There is another important organ that, like the heart, works without interruption.

What kind of organ is this?

Children. These are the lungs there are two people. (Showed in the diagram)

Playback Can a person can live without breathing?

Let's try to hold our breath for a few seconds. Does not work. Means, Human cannot live without breathing.

Guys, when we inhale, we inhale a certain amount of air. It is different for everyone and depends on the volume of the lungs. In adults it is more, and in children it is less.

Do you want to see what lung capacity you have?

A balloon will help us with this. Draw more air into your lungs, and then exhale it into the balloon and immediately squeeze it.

(Children complete the task)

Now we know who has what lung capacity.

Playback So that the body man worked well, everyone must eat. Every day person eats food. From the plate, food falls into the spoon and goes into the mouth. This is where the amazing journey of food begins.

Who will tell me about this journey?

Children. There are teeth in the mouth. They chop and grind food into small pieces. Saliva moistens food so that it can more easily travel down the esophagus to the stomach.

Playback Right. What does the stomach look like?

(children show the organ in the diagram - the stomach)

Playback Right. The stomach digests food and turns it into nutrients that are useful to our body. Food from the stomach

enters the intestines, from where it naturally comes out in the form of residues.

There are many more organs in our body and one of them is the kidneys.

(the child in the diagram shows an organ - the kidneys)

Children. U human two kidneys.

Playback For what a person needs kidneys?

Children. The kidneys cleanse the blood.

Playback Right.

Now I suggest you sit down at the table and find each organ its place.

(Children lay out organs inside the outline person: heart, lungs, stomach, intestines, kidneys).

Playback Now you see that human The body is very complex and everything in it is interconnected.

Playback Who knows what the body needs to the man was healthy, grew and developed.

Children. Human should eat healthy foods that contain various vitamins.

Playback Vitamins are very important for health. There are a lot of them, but the most important ones are vitamins A, B, C, D.

(Children are given a drawing human body. Around there are letters indicating the vitamins contained in the products. A labyrinth line runs from each vitamin to a specific organ.)

Playback Follow the paths of the labyrinth and you will find out which vitamin has a greater effect on which organ.

(Children draw lines)

Vitamin A – vision.

Vitamin B – heart.

Vitamin C – respiratory organs.

Vitamin D – skeleton.

Playback Let's make a vitamin table. Let's select pictures of products that contain the essential vitamins the body needs. person.

What foods contain vitamin A?

What foods contain vitamin B?

(Children choose the right pictures)

What foods contain vitamin C?

(Children choose the right pictures)

What foods contain vitamin D?

(Children choose the right pictures)

Tell us again what foods you should eat

Remember the simple truth -

Only the one who sees better

Who chews raw carrots

Or drinks blueberry juice.

Early morning is very important

Eat oatmeal at breakfast.

Black bread is good for us

And not just in the morning.

Fish oil is the healthiest

No matter how disgusting, you need to drink

He saves from illnesses

Without diseases, life is better!

For colds and sore throats

Oranges help

Well, it's better to eat lemon

Although it is very sour.

I never lose heart

And a smile on your face

Because I accept

Vitamins A, B, C, D.

Now you will always know which foods are best to eat.
