Breathing and the exchange of gases are vital processes that keep our bodies functioning. Breathing involves inhaling oxygen-rich air into the lungs and exhaling carbon dioxide, a waste product. Inside the lungs, oxygen from the air passes into the bloodstream through tiny air sacs called alveoli.

At the same time, carbon dioxide, which the body needs to expel, moves from the blood into the alveoli to be exhaled. This gas exchange ensures that our cells get the oxygen they need to produce energy and function properly, while also removing carbon dioxide to maintain the body’s balance.
