Alveoli Model -
alveoli Alveoli are tiny air sacs that are found in the lungs Oxygen and carbon dioxide move between the air and blood by diffusion in the alveoli
Inhaled oxygen enters the lungs and reaches the alveoli The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick and alveoli Alveoli represent the major sites of gas exchange Their presence increases the surface area of the lung to maximize gas exchange, much like villi and
