Pranayama: what you need to know about the respiratory system?

Breathing is the absorption of oxygen and the elimination of carbon dioxide; it is a process that provides life for all life on Earth. This is confirmed here: Air, as if through a pipeline, enters the trachea. It is located below the larynx and passes into the bronchi, which lead to the lungs. In the lungs, the bronchi branch out, these branches are called bronchioles. Bronchioles supply air to the alveoli, allowing oxygen cells to enter the circulatory system. With the help of the heart, oxygen is distributed throughout the body. Through the same alveoli, carbon dioxide is removed to the outside.

The rib cage has a downward-widening shape. At the bottom of it is the diaphragm – the respiratory muscle. The diaphragm separates the lungs from the abdominal cavity. During inhalation, the chest expands and the diaphragm descends; during exhalation, the chest narrows and the diaphragm returns to its original position. The increase in the chest during inspiration occurs due to the expansion of the ribs to the sides and up.

The lungs are located inside the rib cage and are separated by the heart. The outer parts of the lungs and the diaphragm are covered with pleura – a special enveloping film. The pleura promotes the expansion and contraction of the lungs, prevents friction between the lungs and the chest.

Breathing occurs automatically, thanks to the central nervous system. But we can also control it consciously. Slow and deep breathing is more effective and beneficial for the respiratory system. This is one of the reasons why it is beneficial to practice pranayama.
