Answer :

Final answer:

The process of inhalation and exhalation explained with detailed steps of how the diaphragm and rib cage movement facilitate breathing.


Explanation:

Inhaling:

  • Ribs move out and chest space becomes larger.
  • Diaphragm moves down and air moves into the lungs.

Exhaling:

  • Ribs move in and chest space becomes smaller.
  • Diaphragm moves up and air moves out of the lungs.

During inhalation, the diaphragm contracts, expanding the thoracic cavity and reducing air pressure inside the lungs, allowing air to rush in. Exhalation involves relaxation of the diaphragm, reducing chest volume and increasing air pressure, causing air to be forced out.
