How is air sac designed for the exchange of gases?
Asked by Topperlearning User | 04 Jun, 2014, 01:23: PM
Expert Answer
Structure of air sac or alveoli for the purpose of exchange of gases:
(1) There is a network of blood capillaries surrounding the wall of each alveolus.
(2) The walls of the alveoli are extremely thin (single-celled thick) and moist, thus enabling gaseous diffusion.
(3) Oxygen from the air first dissolves in a thin layer of water fluid that covers the surface of the alveoli.
