Answer 1

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.

Answer 2

Here's Your Answer Frnd-->>

==>> In INSPIRATION ::

• Increased volume of thoracic cavity.

• Incrased volume of lungs.

• Contraction of intercostal muscle.

• Less air pressure insude the lungs in compared to atmospheric air pressure resulting air enters into the lungs.


In EXPIRATION ::

• Decreased volume of thoracic cavity.

• Decreased volume of lungs.

• Relaxation of intercoastal muscle.

• More air pressure inside the lungs in compared to atmospheric pressure resulting air exhale from lungs to atmosphere.
