Capillary exchange diffusion
WebAs the blood is pumped through this capillary network, gas exchange occurs. Although a small amount of the oxygen is able to dissolve directly into plasma from the alveoli, most of the oxygen is picked up by erythrocytes (red blood cells) and binds to a protein called hemoglobin, a process described later in this chapter. WebSquamous epithelium = thin/one cell thick so short diffusion distance. Larger surface area to volume ratio so faster diffusion. Permeable. good blood supply from network of capillaries which maintains the concentration gradient. Elastic tissue which allows it to recoil after expansion. Surfactant
