Exchange of gases occurs between capillaries and what structure?

Answer 1

Exchange of carbon-di-oxide for oxygen takes place between capillaries and tissues.

The exchange of gases occur through diffusion.

In Lungs, oxygen from inhaled air in the alveolar space moves into the RBCs in the capillaries and the carbon-di-oxide moves form the RBCs in the capillaries to the alveolar space which is exhaled during respiration.

In other tissues, the Oxygen is given to the tissues and carbon-di-oxide is taken from the tissues into the blood.

Many gases can be exchanged across the capillaries but the exchange of oxygen and carbon-di-oxide occurs normally in the body.
