TextD

If one investigates the act of inspiration (вдох) one will observe such phenomena.

When one breathes in, the external intercostal muscles contract and lift (поднимать) the ribs. At this moment the diaphragm also contracts and goes down. The volume of the chest increases. The increase of the chest volume enables the lungs to extend. The pressure in the lungs becomes less and the atmospheric air enters the lungs.

When one breathes out, the external intercostal muscles and the muscles of the diaphragm become relaxed (расслабленные). The ribs go down, the diaphragm goes up, the volume of the chest decreases and the lungs contract. The pressure in the lungs becomes higher and the air goes out of the lungs. If one is sitting or lying one makes 16-20 respirations per minute. On physical exertion the respiratory rate and the depth of respiration increase.

Normally during one inspiration the man breathes in about 500 ml of air. On deep inspiration one breathes in 1.5-2 litres of air.

The vital capacity of the lungs in the male averages 3.5-4 litres and in the female 3-3.5 litres.

The respiratory rate and its depth depend on the amount of carbon dioxide in the blood.
