What is the significance of the respiratory system? Their characteristics and functions

What is the significance of the respiratory system in human life? The answer is obvious - the main one. Agree, without food, we can exist for two weeks, without water - from three to five days, without sleep - a few days. If you block the access of oxygen, then in a couple of minutes life can be tragically cut short.

The main role

Breathing organs are the mechanism by which the life of most creatures on the planet is maintained. Without air it is impossible to move around, drink and eat, meet with friends, communicate. Even the slightest defect worsens his well-being: dark circles appear in his eyes, his ears ring, his mind becomes clouded, his legs are shaken. If a person does not breathe for a long period, irreversible changes occur in the brain, the heart stops, physicians fix death.

Oxygen, carried by blood, nourishes every organ and system in the body. It also burns toxins, harmful bacteria and other substances that poison us from within. In addition, he takes the most active part in the regeneration of cells, contributing to the oxidation of blood. Of course, you can not underestimate the importance of breathing. The organs of the respiratory system should be protected, as well as tempered and trained. This is helped by physical exercises and special meditation.

Respiratory system

First of all, these are two lungs. They are located in the subcostal part of the chest. Two lobules of the lungs are separated from each other by blood vessels, breathing tubes and the heart. Each of them has a porous, spongy structure. Inside, they are hollow, with the exception of the vertex, on which are the bronchi, veins and arteries that connect the organ with the heart and the respiratory throat. The lungs are very elastic, covered with a pleura, releasing a special liquid. It is this secretion that serves as a kind of lubricant, which makes it easy to slide the walls of the organ during its operation.

Characteristics of the respiratory system is impossible without describing the ways in which air moves to the lungs. They consist of the nose, pharynx, larynx, trachea and bronchial tubes. If the first element of the system is outside and its structure is known to us, then the rest are located in the depth of the body, so many are interested in knowing how they look and work. For example, the larynx is similar to a funnel, a trachea to a tube, and bronchi to a tree branch. At the ends of the latter there are alveoli - small bubbles filled with air and permeated with blood vessels. Through their walls and gas exchange occurs.

How does the system work?

Features of the respiratory system lie in the complex mechanism of their work, in which we just now try to figure it out. Everyone knows that everything begins with a deep breath, which a person does with the nose. Once in its cavity, the air is heated to body temperature. Here, too, it cleanses of dirt and microbes, which protects the body from the attack of different viruses and bacteria.

Further, air enters the larynx and trachea: the mucous membrane of the latter further clears it of large particles. In the bronchi it continues to be filtered, a cough reflex is formed here, with the help of which evacuation of dust and small foreign bodies from the body takes place. It should be noted and the work of the diaphragm - the unique muscle of the abdominal press, which is similar to an umbrella. When it stretches, the volume of the chest and lungs increases - the air fills the void. During the contraction, it is pushed out. Without the diaphragm, as well as other components of the system, we could not support the vital activity of the body - that is what the value of respiratory organs is.

Oxygen and blood

These are two parts of one whole that help the body to purify itself and to be enriched with useful substances. The blood running from the heart gives the organs everything useful that it contains, so it becomes dirty and dark. When it reaches the lungs, it spreads over a whole network of small capillaries. The flow of air through the walls of the vessels penetrates into the blood: it absorbs the necessary oxygen and is released from harmful carbon dioxide, which is formed from rotting particles collected in all corners of the body.

Purified and enriched with life-giving properties, blood returns to the heart. Through the left ventricle, it flows into the arteries that carry it all over the body. Just think: for one day, 18,000 liters of blood passes through the capillaries. Based on the foregoing, we understand what the significance of respiratory organs is: without the lungs, the supply of clean air to the body is impossible. This entails serious consequences: being dirty, saturated with harmful substances, the blood poisons us from within. And intoxication, in turn, leads to death.

Deep breathing and its role in the body

It is very important for the overall health of a person. If he does not breathe properly, the blood is not cleaned up to the end - the body does not receive the necessary diet. As a result - a disease, a drop in vitality, strength and mood, lack of energy and vivacity. Problems with all bodies begin: in their work there is a failure, they perform their functions at an insufficient level. Further falls immunity: viruses one after another attack your already weakened body. You are treating the consequences in the clinic, not realizing that the original cause is banal - insufficient enrichment of the blood with oxygen.

The significance of the human respiratory system is undeniable. Without sufficient fresh air, blood does not acquire a bright red color, remaining cyanotic and dark. A person loses a lot of weight, looks haggard and tired. And vice versa, the one who breathes correctly and deeply, is distinguished by excellent health and excellent physique. Normally, arterial blood should contain 25% of oxygen.

Oxygen and digestion

You probably have no idea what the value of respiratory organs is for the work of the gastrointestinal tract. By the way, it functions normally only on the condition that the digested food is sufficiently saturated with oxygen. And this happens, of course, only with the help of fresh air, which travels through the blood and with its help gets into the stomach and intestines. Weak and poor digestion are inseparable friends. The body receives useful substances from foods processed and digested by the body. Failure of this function, caused by insufficient intake of oxygen, leads to anemia.

Poor breathing provokes problems in the lungs: they become weak and painful. As a result, the body does not receive the substances necessary for its health and vital activity to a greater degree. A vicious circle is formed, the exit from which is an open and uninterrupted access of a person to a source of fresh air.

Oxygen and immunity

The meaning and function of the respiratory system can not be underestimated. Any doctor will tell you that at the time when the blood is saturated with oxygen, the body burns, caused by the replacement of the spent material. Thanks to this, the body's temperature is kept even, and heat is also stored. People who breathe properly, practically do not suffer from colds. Their veins have enough warm blood, which contributes to adaptation to weather changes. As a result, immunity does not suffer from a drop in air temperature on the street.

The respiratory organs fulfill the role of the so-called scavenger, erupting from the bowels of the body all that is harmful and unnecessary. Therefore, the development of respiratory organs - a pledge of strong immunity and good health.

What happens during sleep?

Strangely enough, but at this time our health is most vulnerable. We go to bed to gain strength, to restore the supply of energy. But often we wake up tired, broken, irritated and angry. All because of the elementary lack of oxygen. Clogging in a cramped room for 8 hours, a person breathes all the harmful substances thrown out by the body. And this is 290 liters of carbon dioxide per night! If two people sleep in a room, then this figure must be multiplied by two.

What is the significance of respiratory organs during sleep? They must also function, filling the body with oxygen. Therefore, they say that sleeping with an open window at any time of the year is a guarantee of health and longevity. The main thing is not to draft. Do not be afraid to catch cold. Remember that modern methods of treatment of tuberculosis are based on a constant stay of the patient in the fresh air, even if the window is cold and bad weather. Cover yourself with several wool blankets: soon you will get used to the temperature and fall asleep in a healthy sleep.

Other recommendations

The meaning and structure of the respiratory system should be known to every person for the preservation of health and the strengthening of immunity. Also, he is obliged to get acquainted with medical recommendations that will help to breathe a full breast, and do it as correctly as possible. In addition to sleeping with an open window, throughout the day, periodically ventilate the room in which you are (at home or in the office). Circulation of air will promote efficiency, preservation of beauty and youth.

Walk a lot. Get out a few stops earlier and walk to the place of work. At lunch time, also stroll through the streets of the city, avoiding dusty roads and highways. For a weekend, make sure you have picnics in the forest. Decorate the interior of the house with pots with living plants: they absorb carbon dioxide and secrete the necessary oxygen. Also, do yoga: special exercises allow not only to stabilize and adjust the work of respiratory organs, but also contribute to finding harmony, peace of mind, give cheerfulness and excellent mood.
