Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going. Although they’re microscopic, alveoli are the workhorses of your respiratory system.You have about 480 million alveoli, located at the end of bronchial tubes. When you breathe in, the alveoli expand to take in oxygen. When you breathe out, the alveoli shrink to expel carbon dioxide.Although tiny, the alveoli are the center of your respiratory system’s gas exchange.There are three overall processes involved in your breathing: moving air in out of lungs, oxygen-carbon dioxide exchange, and pumping blood through your lungs.The alveoli pick up the incoming energy (oxygen) you breathe in and release the outgoing waste product (carbon dioxide) you exhale. As it moves through blood vessels (capillaries) in the alveoli walls, your blood takes the oxygen from the alveoli and gives off carbon dioxide to the alveoli. These tiny alveoli structures taken all together form a very large surface area to do the work of your breathing, both when you’re at rest and when you are exercising. The alveoli cover a surface that measures more than 1076 square feet (100 square meters).
