Question

5.What changes are observed in diaphragm during inhalation?

Answer 1

Answer:

During inhalation, the diaphragm contracts, so that its center moves caudally (downward) and its edges move cranially (upward). This compresses the abdominal cavity, raises the ribs upward and outward and thus expands the thoracic cavity. This expansion draws air into the lungs.

Answer 2

Answer:

During inhalation, inhaled air enters the lungs,so the diaphragm expands from it's normal state. but it won't last for a long time. when you exhale the CO2, the diaphragm retains to its normal shape.
