Answer: lower atmospheric pressure

Explanation:

During the inspiration process the diaphragm, and external intercostal muscles. The contraction of the diaphragm causes the increase in the size of the thoracic cavity this causes the contraction of the external intercostal muscles. As a result of this the ribs and the sternum get elevated.

Thus this facilitates the movement of the gases from a region of high pressure to low pressure, this way the air rushes into the lungs.
