Oxygen and carbon dioxide are transported between the blood and alveoli by way of

• exocytosis and endocytosis by endothelial cells

• diffusion from areas of higher concentration to lower concentration

• pinocytosis using fluid-filled vesicles

• active transport (using ATP) by protein carriers of endothelial cells
