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
1. Alveoli are composed of epithelial layers and extracellular matrix enclosed in capillaries while alveolar sacs are the distal ends of alveolar ducts. 2. The alveoli sacs are formed by a group or cluster of alveoli, and it is there where they communicate while the alveoli are made up of collagen and elastic fibers..
