PATHOLOGY

Detailed explanation-1: -The lungs absorb oxygen during inhalation and expel carbon dioxide during exhalation. The air that is exhaled out is also a mixture of gases but it is rich in carbon dioxide.

Detailed explanation-2: -Exhalation: When you breathe out, or exhale, your diaphragm relaxes and moves up into your chest cavity. As the space in your chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out your nose or mouth.

Detailed explanation-3: -The percentage of CO2 in inhaled air is 0.04% whereas in exhaled air it is 4.4%. Therefore, we can say that exhaled air has more percentage of carbon dioxide than in the inhaled air.
