ANATOMY

Detailed explanation-1: -The main reason for exhalation is to rid the body of carbon dioxide, which is the waste product of gas exchange in humans. Air is brought into the body through inhalation. During this process air is taken in by the lungs.

Detailed explanation-2: -This is important because if we couldn’t remove carbon dioxide from our blood, it would take up all the carrying capacity of our blood and we wouldn’t be able to get oxygen to the rest of our body.

Detailed explanation-3: -Lungs Hard at Work The oxygen circulates in your body, gets used up, and carbon dioxide is the result. The carbon dioxide then travels with your blood back to your lungs and is diffused to the alveoli, where it is exhaled.

Detailed explanation-4: -Carbon dioxide diffuses from the cells into the blood. Deoxygenated blood is carried by the veins towards the heart. It enters the right side of the heart and is pumped into the pulmonary system. Carbon dioxide diffuses into the lungs and is expelled as we exhale.

Detailed explanation-5: -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.
