Question

1) List three characteristics of lungs which make them an efficient respiratory surface

Answer 1

Three Characteristics Of Lungs Which Make Them An Efficient Respiratory Surface Are:
1.They Have A Rich Blood Supply.
2.Their Inner Surface Is Moist.
3.They Have Large Combined Surface Area.

Answer 2

The three characteristics of lungs that make them an efficient respiratory surface are-

1) Large surface area - Lungs have a huge quantity of alveoli that enhances the surface area needed for the transfer of gases.

2) Thin walls - There is a single sheet of cells available in the alveolar surface which provides gases a short dissemination distance.

3) Extensive blood supply - There is widespread blood accumulation in the lungs, which guarantees that oxygen-rich blood is carried away from the lungs and blood rich in carbon dioxide is carried to the lungs.
