The meaning of breathing exercises, what are the three links of breathing exercises

The lungs exchange gases with the outside world to provide oxygen for the metabolism of tissue cells and excrete carbon dioxide at the same time.

The three stages of the breathing process:

1. The exchange of gas between the outside air and the alveoli and between the alveoli and the blood of the pulmonary capillaries, which is called external respiration;

2. The transportation of gas in the blood, through the operation of the blood, on the one hand, the oxygen ingested by the lungs is transported to the tissue cells in time, and on the other hand, the carbon dioxide produced by the tissue cells is transported to the pulmonary capillaries for excretion;

3. Gas exchange between blood and tissue cells.

Proper breathing is at the heart of all pranayama regimens, and it is an important action that needs to be used throughout the various exercises. Scientific breathing can double the effect of exercise. There is a distinction between static and dynamic breathing, and breathing at rest is generally called "pranayama".

Principle process of breathing movement:

Due to the relaxation of the respiratory muscles, the chest cavity is regularly expanded and contracted, alternating movements. It consists of two processes: inhalation and exhalation. The basic meaning of breathing exercise is to make the gas in the lungs communicate with the external gas, effectively provide the oxygen required for the body's metabolism, and expel the carbon dioxide produced in the body.

The main respiratory muscles involved in respiration are the diaphragm, external intercostal muscles, internal intercostal muscles and abdominal wall muscles. During peaceful inhalation, the diaphragm and external intercostal muscles contract, causing the anterior, left, right, and upper and lower diameters of the chest cavity to increase, and the lungs to expand accordingly, forming an active inhalatory movement. When the diaphragm and external intercostal muscles relax, the ribs and sternum return to their own gravity and elasticity, resulting in a shrinkage of the thoracic cage and a retraction of the lungs, resulting in a passive expiratory movement.

There are two types of breathing exercises: chest breathing and abdominal breathing, the former is dominated by intercostal muscle activity, which is manifested by the undulation of the chest wall; The latter is dominated by diaphragmatic activity, which is characterized by the undulation of the abdominal wall. In general, adult women mainly breathe in the chest breathing, while babies and men tend to breathe in the abdomen.

Respiratory movements are influenced by the surface of the breathing:

1. Thin surface: convenient for gas diffusion.

2. Damp surface: oxygen must be dissolved in water before it can be absorbed into the blood in the body. The same carbon dioxide must be dissolved in water in order to diffuse out of the body.

3. Large surface area: to accelerate the exchange rate of gas.

4. Dense microvascular network: convenient for the transportation of gas after exchange.

Gas Exchange Principle:

The process by which organisms inhale oxygen from the environment into the body and at the same time excrete carbon dioxide from the body into the environment is called gas exchange Single-celled protozoa exchange gas between the body surface and water by inhaling the dissolved oxygen in the water into the body and excreting the carbon dioxide from the body into the water at the same time The higher multicellular animals, including humans, constantly exchange gas between the air in the alveoli and the venous blood in the capillaries of the lungs through respiratory movements and blood circulation The whole process can be divided into two aspects: internal breathing and external breathing.

Gas exchange is affected by the breathing surface:

Thin surface: facilitates the diffusion of gases.

Damp surface: Oxygen must be dissolved in water before it can enter the bloodstream in the body. The same carbon dioxide must be dissolved in water in order to diffuse out of the body.

Large surface area: to accelerate the exchange rate of gases.

Dense capillary network: facilitates the transport of gas after exchange.

Breathing is one of the characteristics of living things.

Breathing exercise is the contraction and relaxation of respiratory muscles such as intercostal muscles and septum, which causes the thoracic cage to expand and contract.

Respiration refers to the use of oxygen by plant cells to decompose organic matter into carbon dioxide and water, and release the energy stored in organic matter to meet the needs of life activities.
