उत्तर
A human adult at rest, on average, breathes about 12-20 times per minute i.e. 28800 times per day. The mechanism of breathing in human beings involves two processes: Inhalation and Exhalation.
Inhalation: When the muscular diaphragm of the body relaxes, the volume of the thoracic cavity increases and air pressure inside the cavity decreases. The air from outside enters the lungs through the nostrils and the alveolar sacs are filled with air rich in oxygen.
