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. People have an average of 480 million alveoli in their lungs, located at the tip of bronchial tubes. While you breathe in, the alveoli increase to absorb oxygen. While you breathe out, the alveoli shrink from expelling carbon dioxide. Although tiny, the alveoli are the middle of your respiratory system’s gasoline change. The alveoli pick up the incoming oxygen you breathe in and launch the outgoing waste product (carbon dioxide) you exhale. Because it moves via blood vessels (capillaries) in the alveoli partitions, your blood takes the oxygen from the alveoli and offers off carbon dioxide to the alveoli. These tiny alveoli buildings, taken collectively, kind a really massive surface area to do the work of your respiration when you’re resting and exercising. The alveoli cover a surface of more than 1,399 ft (ft) or 130 square meters (m2).
