Which is an active provess?why

Answer 1

Answer:

hope it helps you

Explanation:

Inspiration is an active process whereas expiration is a passive process. Inspiration occurs when the muscles of the diaphragm contract to increase the overall volume of the thoracic cavity. ... As the muscles use energy for contraction, inspiration is called active process.

Answer 2

Inspiration is caused by the contraction of muscles of diaphragm causing it to move downwards thus enlarging the chest cavity. since pressure is inversely proportional to volume, thus pressure drops below the outside pressure and air. Whereas

expiration is relatively opposite: the diaphragm passively relaxes and chest volume decreases causing an increase in air pressure inside the lungs
