The alveoli are located in the lungs. They are used to move carbon dioxide and oxygen between the lungs and the bloodstream.

Alveoli are tiny air sacs that are grouped like grapes, except they are on an upside down "tree" like structure. Air flows into the lungs. RBCs in capillaries exchange oxygen and carbon dioxide at each alveolus-- millions of molecules at once. The sole purpose of these tiny sacs is exchange of gases. If they flatten, like in COPD, the person receives less oxygen.

The alveoli are one of the reasons we are able to inhale/exhale 02 a co2. The alveoli fill up with oxygen that you breathe in. The oxygen from inside the alveoli then diffuses into the blood stream oxyeginizing your blood, so oxygen can get to many vital organs. Co2 also leaves your body through the reverse process.

The alveoli are specialised cells in mammalian lung tissue which are the main site of gas exchange between air and blood. They are the final bifurcation of the bronchial tree and sit on a bed of capillaries. They have been adapted to optimise the parameters of Fick's Law (diffusion distance and concentration gradient). Their cell wall is very thin and in close contact with the pulmonary circulation and this blood is continually flowing past in order to maintain a constant concentration gradient.

The alveoli replaces CO2 with O2. Then the circulatory system delivers the O2 to the cells in your body.

The alveoli are small bulbous air sacs in the lungs. Their primary function is to facilitate gas exchange to and from the blood stream. Oxygen is passed in and carbon dioxide is extracted.
