What Is the Difference Between Inhalation and Exhalation?
Inhalation is the process of bringing air into the lungs while exhalation is the process of pushing the air out of the lungs. Inhalation helps the body bring in oxygen and exhalation helps the body expel carbon dioxide.
Breathing is the process of inhaling air through the nose or mouth. The air moves down the throat and into the trachea and then divides into the bronchial tubes. The bronchial tubes divide out into smaller passages called bronchioles as the bronchial tubes go through the lungs. The bronchioles have air sacs at the end called alveoli, which are surrounded by capillaries. Capillaries are small blood vessels that air passes into when it reaches the alveoli walls. The air goes into the blood and as the cells use the oxygen they produce carbon dioxide. The blood carries the carbon dioxide back to the lungs, and it is removed from the body during exhalation.
