The alveoli are the sites of gas exchange they are located at the terminal regions of the lung and are attached to the respiratory bronchioles.
Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli. Gas exchange occurs within the lower airways, primarily the alveoli. Often called the business end of respiration. Blood entering the lungs via the pulmonary artery is deoxygenated. It becomes oxygenated when the capillaries pass through the alveoli and reenters the heart via the pulmonary vein with oxygenated blood.
