Alveoli help in gaseous exchange. They are characterised by extremely thin walls, large surface area in relation to volume, fluid that lines them enabling gases to dissolve and numerous capillaries surrounding them.
Alveoli are tiny air sacs with a form of hollow cavity and are located at the end of the respiratory tract. They are mainly involved in gas exchange and carrying of de-oxygenated blood to the lungs to be re-supplied with oxygen.
The function of the alveoli is to facilitate gaseous exchange of oxygen and carbon dioxide. Oxygen from the drawn in air circulates through the walls of the alveoli and nearby capillaries into the red blood cells.
