PATHOLOGY

Detailed explanation-1: -Inhaled air contains approx 21%oxygen, 0.04% carbon dioxide and 79%nitrogen while exhaled air contains approx 16% oxygen, 4% carbon dioxide and also 79% nitrogen. The only difference between them is the varying levels of oxygen and carbon dioxide. The inhaled air is actually a air.

Detailed explanation-2: -The amount of inhaled air contains 21% of oxygen and 0.04% of carbon dioxide, while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide. This is because our cells use oxygen from the inhaled air to release energy and give out carbon dioxide as a byproduct.

Detailed explanation-3: -Answer: The exhaled air contains more carbon dioxide because the carbon dioxide produced during respiration is removed out of the body as the exhaled air during the process of respiration.
