Question

explain the process of inhalation and exhalation

Answer 1

when we inhale our lungs contract and the diaphram shrinks.when we exhale the our lungs relax and the diaphram also relaxes

Answer 2

Explanation:

When the diaphragm contracts, it moves down towards the abdomen. This movement of the muscles causes the lungs to expand and fill with air, like a bellows (inhalation). Conversely, when the muscles relax, the thoracic cavity gets smaller, the volume of the lungs decreases, and air is expelled (exhalation).
