Expert Answer:

Carbon dioxide gas diffuses out of the body cells into the capillaries.
It is then transported as follows:
1. 7% of it is transported as dissolved gas in the blood plasma and into lungs.
2. 70% enters the RBCs and reacts with water to form carbonic acid, gets dissociated to form bicarbonates and hydrogen ions. The bicarbonate ions then enter into the plasma.
3. Rest 23% combines with the globin part of heamoglobin to form carbaminoglobin which is transported into the lungs.
