alveoli are small air sacs in the lungs as small as a grain of sand there are billions of these in the lungs and the purpose of these alveoli are to supply de oxygenated blood with a supply of oxygen through gas exchangethey are well equipped to do this as well00 million to 400 million alveoli are in each lung each of the alveoli receives blood from the circulatory system capillaries it replaces carbon dioxide and other blood was tes with oxygen
An alveolus is a hollow cavity found in the lung parenchyma, and is the basic unit of ventilation. Lung alveoli are the ends of the respiratory tree, branching from either alveolar sacs or alveolar ducts, which like alveoli are both sites of gas exchange with the blood as well. Alveoli are particular to mammalian lungs. Different structures are involved in gas exchange in other vertebrates. The alveolar membrane is the gas exchange surface. Carbon dioxide rich blood is pumped from the rest of th
