3. Main part.

The French poet Pierre Jean Beranger said that

“Health is the fee of the wise.” How do you understand this?

What is a fee?

Let's find an explanation of the meaning of this word in the explanatory dictionary. Read it.

FEE is a monetary reward under a contract or agreement for work.

Is it possible that someone pays him money for the fact that a person is healthy?

Listen carefully to the poem.

What kind of life did the hero of this poem lead?

Guys, can you call yourself a healthy person? Why? How do you keep yourself healthy? (answers)

Can our hero still be helped? Let's help and build a foundation of health for this boy.

After all, human health, like a large building, is built from individual elements. These elements form the foundation of our health, and without them the full existence of a large house like our body is impossible.

4. Work in groups (2 groups)

You have bricks. Choose those that will form the foundation of the boy’s health.

For example, to maintain my health, I try to be physically active and cheerful, this is what I advise our hero, and now you...

(Students select the necessary bricks and attach them to the board as a foundation.)

We have laid the foundation. These are the main factors of health.

Can he be healthy now? Under what conditions? (if he follows these tips). What kind of life should he lead?

You can also learn about healthy lifestyles from various information sources. (Please note the book exhibition)

You still have bricks on the tables. Why did you leave them?

Everything we have listed is harmful to health.

So, Health is a priceless gift. A person who values ​​his health and takes care of it is considered wise.

Wise people pass on their knowledge and experience to other people by putting together proverbs and sayings.

6. Proverbs.

8. Summary (reflection).

What great fellows we are! Today we talked about human health. We found out that health is the most important value for a person.

Is it important to lead a healthy lifestyle? Why? What do you need to do for this? (answers)

Let's return to the topic of our lesson:

“HEALTH IS THE FEES OF THE WISE”

During the classes

1. Organizational moment.

Guys, we are finishing our study of the section “We and our health.”

Let us remember that at the beginning of studying the section we set a goal (table on the board):

I want to know:

1. What is a living organism? What are the characteristics of the human body?

2. What organs are there in the human body? What is their function?

3. What do organs form when performing general work?

4. What do sciences do: anatomy, physiology, hygiene?

5. What should you do to be healthy?

Today in class we will try to summarize our knowledge about the human body. Let's see how you know the structure of the human body, the rules of leading a healthy lifestyle.

2. Work on the topic uro ka.

Teacher. For many centuries, humanity has been searching for an answer to the question of what life is. Perhaps, even today this question remains one of the most important, because the answer to it is by no means always unambiguous.

Man is a part of nature, its living world.

Slide 3.

Do you agree with this statement? Prove it.

(Like other living beings, he breathes, eats, grows, develops, has children, and dies)

Slide 4.

But we know that humans are still different from animals. How? Name the main features.

Slide 5.

According to Ozhegov’s dictionary: “An organism is a living whole that has a set of properties that distinguishes it from inanimate matter.”

Slide 6.

You and I live in the world without thinking particularly about how we are structured. It seems like everything is very simple. But you already know what complex work happens in your body.

Why do we need to know the structure of the human body?

Page "Musculoskeletal system"

Slide 7.

The musculoskeletal system (the teacher points to the textbook “Skeleton”) is formed by the skeleton (bones) and muscles.

What is the purpose of the human skeleton? (The human skeleton serves as the internal support of the human body and protects internal organs from damage)

What is the importance of the skeleton and muscles for a person? (Provide a certain position of the human body in space - posture and mobility.)

Why does my posture deteriorate? (Improper sitting at a desk; carrying heavy objects in one hand, etc.)

What rules must be followed to ensure correct, good posture? (Sit correctly, straight; carry weights in two hands or behind your back, etc.)

Don't forget about the rules of posture, sit correctly, show me your posture.

Thank you. What organs does the chest protect? (It protects the lungs and heart)

So, let's remember the main organ systems of the human body.

Page "Respiratory system"

Slide 8.

All his life a person breathes - inhales and exhales air. Name the respiratory organs in order of the airway. (Nasal cavity, nasopharynx, larynx, trachea, bronchi, lungs). Show them on the layout.

Place both hands on your lungs. Take a deep breath and exhale.

Tell us briefly about the journey of air.

What is the main function of the respiratory system?

Page "Circulatory system"

Slide 9.

Blood plays a huge role in the body. It brings nutrients and oxygen to all organs, and removes carbon dioxide from them.

Name the circulatory organs. (Heart and blood vessels). Show a heart on a model of a person.

Place your right hand on your heart. Do you feel it knocking?

Tell us how the heart works. (The heart is a muscular organ that can be compared to a pump. It forcefully pushes blood into the blood vessels. Having traveled throughout the body, the blood returns to the heart. It sends it to the lungs, and then again makes it travel throughout the body. The heart works continuously throughout life person.)

3. Physical education minute.

4. Continuation of work on the topic of the lesson.

Page "Digestive system"

Slide 11.

The human body is constantly using up nutrients. All organs need nutrients. Therefore, the human body needs nutrition. The digestive system is called the “inner kitchen” of the body.

List the digestive organs. (Oral cavity, pharynx, esophagus, stomach, small and large intestines, rectum, liver.) Show them on a model of a person.

Place your left hand on the place of your body where your stomach is, and your right hand on the place where your liver is.

Let's discuss what each digestive organ serves.

Slide 12.

What nutrients does a person get from food? (Proteins, fats, carbohydrates, and vitamins.)

What is their role and in what products are they found?

Page "Excretory system"

Slide 13.

Unnecessary waste from the body (sweat, fat, urine, feces, carbon dioxide) leaves it.

Let's put both hands on the lumbar region of our back, where our kidneys are located.

What is the main function of the excretory system?

Nervous System Page

Slide 14.

Our body listens to us. If you want, you will sit down; if you want, you will run. There is a “main command post” for the life of the human body. What organs am I talking about? (brain: head and spinal)

That's right, it's the brain and spinal cord. Where is the brain located? (In the skull) Where does the spinal cord go? (In the spinal column). Show the location of the brain on a human model.

What are nerves used for in the human body? (To transmit commands from the brain to all organs)

Page "Sense Organs"

Slide 1 5.

What organs help a person navigate the world around him? (sense organs)

Our body is equipped with 5 sense organs. With their help, we receive all the information about the world around us.

Music is playing.

Listen. What did you hear? How do we hear sounds? Sounds travel through the ear to the eardrum, and then the nerve endings transmit information to the brain. And we begin to distinguish and understand what kind of music is: quiet or loud, fast or slow. So, guys, the first feeling is... (hearing).

Now look around, what do you see? Now close your eyes, what do you see? With what help do we see? Light enters the eye through the pupil and is focused by the lens on the back wall. It is covered by the retina, the light-sensitive cells of which perceive the image and transmit it to the brain along the optic nerves. It is with the help of vision that we distinguish objects, their shape, color, size. This is guys, the second feeling is…. (vision).

Now take a lemon, take a bite, how did you feel? And with the help of what organ did we determine the taste of lemon? There are tiny pimples on the tongue called taste buds. Their sensory cells allow us to detect the taste of food. Each type of it - bitter, sweet, sour and salty - is perceived by a strictly defined part of the tongue. The tongue helps us distinguish the taste of food. It's delicious, I'll eat it sweetly. But no, it’s not tasty. This third sense is ... (taste).

Next, take a piece of soap, smell it, what do you feel? What did we use to smell it? There are receptors in the nose that transmit odor signals to the brain. This fourth sense is... (smell).

When we feel an object, sensory cells in the skin tell the brain whether it is hard or soft, dry or cold, smooth or rough. Now run your hand over the tabletop and tell me what it feels like? This fifth sense is... (touch).

So, name the sense organs and their functions. (The eyes are the organ of vision, the ears are the organ of hearing, the nose is the organ of smell, the tongue is the organ of taste, the skin is the organ of touch.)

Page "Test"

Slide 16.

Prepare cards with the numbers “1”, “2”, “3”. I will read the question and three possible answers to it. You must choose one correct answer and show the card with the answer number.

1) What internal organ is called the “motor” of the whole organism?

1- heart 2- lungs 3- brain

2) The internal organ that manages all the thoughts and feelings of a person, monitors the proper functioning of the organs - this is...

1- stomach 2- liver 3- brain

3) This paired organ is compared to a sponge due to its porous structure...

1- brain 2- heart 3- lungs

4) The neighbor and assistant of the stomach is located on the right side of it...

1- pharynx 2- liver 3- trachea

5) Which organ is not an excretory organ...

1- kidneys 2- skin 3- heart

1- Your heart is the size of your fist.

2- Esophagus - respiratory organ

3- The main compartment of the “inner kitchen” is the stomach.

4- The winding labyrinth of the “inner kitchen” is the brain.

5- The trachea and bronchi are the digestive organs.

Well done!

Page "Human Sciences"

Slide 17.

The science of biology studies nature. What sciences study humans?

Complete the sentences with the names of sciences:

The structure of the body is studied by science (anatomy).

The work of organs and organ systems - ... (physiology).

The science of maintaining and promoting health - ... (hygiene)

Slide 18.
