What is the structure of a capillary?

How many layers thick is a capillary?
One cell thick
Gas exchange occurs at the respiratory membrane between the?
The membrane of the alveolus, the air sacs in the lungs where this process takes place, is only one cell thick. The wall of the capillary running adjacent to the alveolus is also one cell thick, so the gases are exchanged between the alveolus and the capillary cell membranes.

How does capillary wall receive oxygen?
