I. Organizational moment (2 min.)

Introductory speech of the teacher. Good afternoon guys! I am glad to see you in health and with smiles on your face.

II. Motivation and preparation for learning new material (5 min.)

Today we start to study the next section of the course of biology "Breathing".
We will begin by clarifying the meaning of the respiratory process and get acquainted with the structural features of the human respiratory system.
Write the topic of the lesson in a notebook. (slide 1)

The topic "The structure of the respiratory system"

The goals and objectives of the lesson are discussed (slide 2) ... Pay attention to the blackboard, the main goal of our lesson is written on it.

As an epigraph to our lesson, I would like to take the words of the ancient Roman poet Ovid (slide 3) .

Joint goal-setting

A person can live without food for several weeks, without water - for several days (3 days), without oxygen - no more than 3 minutes. Why? (slide 4) .
To answer this question, let us turn to the study of the structure of the respiratory system.
You have instructional cards on your tables, look at card # 1. What kind do you know the respiratory organs of a person? Underline those that, in your opinion, can be attributed to the respiratory organs.

Card 1

III. Assimilation of new knowledge (23 min.)

1. The concept of breathing.

So what is breathing? (slide 5). We write down a short definition in a notebook.

2. The structure of the respiratory system.

A person breathes with the help of the lungs - the main organ of gas exchange in our body. But the air to them passes a certain path, which we have to study.

Let's turn to the table "The structure of the respiratory system" and see the location of these pathways. Using card number 1, we will determine which of them are referred to the top, and which - to the bottom.

Complete the diagram on card 2.

Card 2

Check the execution of card 2 (slide 6) .

In the process of studying the structure and functions of the respiratory system, we will formulate the knowledge gained in the form of a table.

Respiratory organs and their functions

Explanation of the teacher using a table.

The guide to the respiratory system will be a terminological dictionary, and the guide will be an air bubble from Novokuznetsk. What are the features of the air in our city? (dustiness)

Air enters the body through the nasal passages surrounded by nostrils (slide 7) .

What will we see in the nasal cavity? (slide 8)

The walls of the nasal cavity form an uneven relief. Each half of it has a lower, middle and upper nasal passages. Due to this, the area of ​​contact of air with the outer layer of cells of the mucous membrane increases.

1. The epithelium lining the nasal cavity is called ciliated. Why? (His cells have cilia)
2. What are its functions? (Traps dust and other particles)
3. What is the body's reaction to dust? (sneezing and coughing)

What happens to the air in the nasal cavity? (slide 9).

Assignment: propose a record of the functions of the nasal cavity in an abbreviated version and enter them in the table.

Let's listen to a message on the topic “Infectious and Chronic Upper Respiratory Diseases”.

Let's do a little research and check the air permeability through the nasal passages (slide 11).

From the nasal cavity, air enters the nasopharynx, then into the mouth of the pharynx and then into the larynx.

Is there further purification and humidification of the air here? (Yes)

What happens to the bubble then? It will go into the larynx.

It has a complex structure and is formed by cartilage, ligaments and muscles. (slide 12).

The largest cartilage - the thyroid (why is it called that?) - forms an angle - the Adam's apple; below - cricoid; above the entrance to the larynx - the epiglottis .

Let's try to figure out the role of the epiglottis in swallowing and conduct the following experiment (slide 13).

Exercise. Explain the meaning of the saying "When I eat, I am deaf and dumb" (slide 14).

The epiglottis covers the entrance to the larynx and prevents food from entering the respiratory tract. This happens during swallowing. With the action of special muscles, the epiglottis tilts and closes the entrance to the larynx. Food slips into the esophagus.

And if you choked on unintentionally, how can you help such a trouble? (slide 15).

Take a close look at the picture on page 139. What interesting things do you see in the larynx? (vocal cords). How is sound produced?

Let's watch a video clip about this (slide 16).

Let's do another research (slides 17 and 18).

1. What other organs are involved in the formation of speech? (Tongue, teeth, lips, cheeks, muscles of the larynx)
2. What causes voice disorders? (colds - laryngitis, pharyngitis and others; heavy load on the vocal apparatus of singers, actors, announcers, teachers - people of "speaking" professions, smoking, alcohol) (slide 19).

1. Do not sing long and loud.
2. Do not shout. Cultivate a culture of conversation.
3. No smoking.
4. Temper, keep away from colds .

Suggest recording the functions of the larynx. Put them in the table.

Now let's have a little rest! (slide 20).

Where do you think the air gets from the larynx? Into the trachea.

The trachea in an adult has the shape of a tube 10-13 cm long and serves for the passage of air into the lungs and back.

Assignment: Read the text on page 139, look at the picture and answer the questions.

What is the trachea formed by? (16–20 cartilaginous half rings)

The epithelium lining the trachea is called ciliated, since its cilia make 10-15 swings per second in the opposite direction and move dust particles that enter the air along with mucus up the pharynx, where they are swallowed or removed outside (slide 21). Scientists have calculated that half a bucket of dust would have accumulated in the human lungs by the end of life, if not for the activity of these cilia.

What is behind the trachea? (esophagus).

Why should food be chewed thoroughly? (slide 22) ... The trachea and the adjacent esophagus are separated by a thin muscular wall.

A large piece of food stretches it and blocks the airways, which leads to a lack of oxygen.

Suggest a record of the functions of the trachea and write it down in the table.

The lower end of the trachea is divided into two thinner tubes - bronchi (right and left). The bronchi gradually branch into smaller and smaller ones, reaching the thinnest branches - bronchioles, forming a bronchial tree - a dense network of branched bronchi (slide21) .

Suggest an entry in the table about the functions of the bronchi.

And where will the bubble end its journey? In the lungs.

They are located in the chest. The surface of the lungs is covered with a special membrane - the pulmonary pleura, the chest is lined with parietal pleura, between them there is a pleural cavity (hermetically sealed), filled with pleural fluid.

The bronchioles end in sacs, the walls of which are formed by pulmonary vesicles - alveoli. From the inside, the alveoli are covered with a special substance (surfactant), which prevents the alveoli from collapsing during exhalation.

What effect does smoking have on the lungs? (slide 23)

Record basic lung function in a table.

Find card number 3 in the instructional card and let's repeat the respiratory organs indicated by the numbers.

Now back to the problem of our lesson (slide 24). Why can't a person live without oxygen? Is knowledge only about the structure and functions of the respiratory organs sufficient to solve this problem? No. It is also necessary to clarify the role of oxygen in our body. To do this, we turn to its chemical properties. (slide 25).

Oxygen is a good oxidizing agent. Oxidizes simple and complex inorganic substances, for example:
2CO + O 2 = 2CO 2
But not only inorganic, but also organic (BZHU), for example:
С 6 Н 12 О 6 + 6О 2 = 6СО 2 + 6Н 2 О + Q (where Q is energy)

Energy is generated.

In cells, this energy is used for the vital functions of cells. If the oxygen supply is cut off, what will happen to the cell?

The cells will die, which will lead to the death of tissues and, consequently, organs. This is why oxygen must be continuously supplied.

So what is the biological significance of breathing? (slide 26).

Let's once again repeat the structure of the respiratory system and watch a video clip about our journey (slide 27)

We have completed the study of the anatomical structure of the human respiratory system. Look again at the lesson goal on the chalkboard. What new have you learned today? (the structure of the respiratory organs, their names, classification, functions performed, respiratory and voice hygiene, the importance of breathing, and also revealed the dependence of the structure on functions).

Why do you think you need this knowledge? Where can you apply them? (when providing first aid, adherence to the rules of personal hygiene).

Now I propose to check the assimilation of the acquired knowledge. Answer the compliance test questions on the guidance card. Let's check the correctness of the answers together (mutual control).
