Explain the structure and function of the respiratory membrane
What will be an ideal response?
The respiratory membrane, also known as the air-blood barrier, is comprised of the fused basement membranes of the alveolar and pulmonary capillary walls. The respiratory membrane has gas flowing past on one side and blood flowing past on the other. Gas exchanges occur by simple diffusion through the respiratory membrane. Oxygen passes from the alveolar air into the capillary blood and carbon dioxide leaves the blood to enter the gas-filled alveoli.
