Question

state 2 features of respiratory area which can maximize the exchange of gases?​

Answer 1

Answer:

The alveoli are thin walled and richly supplied with a network of blood vessels to facilitate exchange of gases between blood and the air filled in alveoli. They have balloon – like structure that provide maximum surface area for exchange of gases.

Answer 2

the thinner is the wall of the alveoli the more is the amount of exchange of the gas. In addition to this the more the concentration difference between the gases the more is the exchange.

Explanation:

• The exchange of gases in the lungs takes place by the process of diffusion. Diffusion depends on several factors.

• One of the factor is the  thickness of the membrane. The other factor is the amount of diffusion is is directly proportional to the surface area of the exchange. It also depends on the concentration gradient.
