Question

explain how lungs are efficient respiratory surfaces

Answer 1

Answer:

Large surface area: Lungs provide a large surface area in the form of alveoli inside for the exchange of gases by diffusion. This helps in the absorption of oxygen.

Large surface area: Lungs provide a large surface area in the form of alveoli inside for the exchange of gases by diffusion. This helps in the absorption of oxygen.Thin walls: The air sacs/alveoli are thin which allows the quick diffusion of the gases through it.

Rich in capillary supply: The alveoli are richly supplied with the capillaries that bring blood with the carbon dioxide and absorbs oxygen.
