Moist walls.
Capillary network on surface of aveoli.

Question 6

In the human body, anaerobic respiration is performed at a certain time; when is it performed?

Answer 6

When the oxygen demand is higher than the oxygen supply.

Question 7

How does carbon dioxide in the blood transfer from the capillaries to the aveoli to get exhaled?

Answer 7

Diffusion; air in the aveoli has a higher concentration of oxygen and lower concentration of carbon dioxide which allows the respective molecules to go to the place with the lower concentration.
