Answer 1

Answer:

Process of inspiration.

Explanation:

It is the process of taking air from the atmosphere into the lungs .it is done by creating a pressure gradient between the lungs and the atmosphere .

DURING, inspiration the Diaphragm contracts and the space in the thoracic cavity is increases .

Along with this, there is contraction of external internalcoastal muscles.

This results in the outward movement of ribs and the sternum .This increases the volume of thoracic in the dorsoventral axis.This ultimate increase in the pulmonary volume .

Due to this intrapulmonary volume pressure become lessser than the atmospheric presssure .

This causes the inhalation of air from the atmosphere in to the lungs.
