Answer:

how does expiration takes place?

Inspiration occurs when intrapulmonary pressure falls below atmospheric pressure, and air moves into the lungs. ... Expiration occurs when intrapulmonary pressure is increased above atmospheric pressure. After the diaphragm contracts, it relaxes, thus decreasing thoracic volume and increasing intrapulmonary pressure.

Explanation:

The process of breathing (respiration) is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation). ... During expiration, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases. As a result, the lungs contract and air is forced out.
