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
Alveoli. The epithelium of the alveoli, contains two main types of cells: 1. type I pneumocytes: large flattened cells - (95% of the total alveolar area) which present a very thin diffusion barrier for gases.They are connected to each other by tight junctions.2. type II pneumocytes (making up 5% of the total alveolar area, but 60% of total number of cells).lveoli.
