The capitularies are responsible for bass exchange
The veins and arteries.
The capillaries are responsible for gas and nutrient exchange with each of the body's cells.
Gas exchanges
in your respiratory system
The exchange of gases occurs at the ends of the airways in the lungs. Here tiny sacs called alveoli connect with tiny blood vessels and here exhaust gas [carbon dioxide] is exchanged for fresh gas [oxygen].
The lungs.
Diffusion.
When two vessels are operating in the same general area both vessels are responsible for maintaining a sharp look out.

The capillaries are where the gas and nutrient exchanges occur. Because in a closed circulation system the blood can't go outside the vessels, it must go to the capillary beds where it is about 1 cell thick to have diffusion. Alveoli in lungs are covered by capillaries to allow gas exchange to happen. The capillaries are most abundant of all the blood vessels, because most part of your body requires oxygen, and capillaries are where it can be given to cells.
