Most important from of carbon-dioxide transport in the blood
The route by which most of the carbon dioxide is carried in the bloodstream. Once dissolved in the blood plasma, carbon dioxide combines with water to form carbonic acid, which immediately ionizes into hydrogen and bicarbonate ions. The bicarbonate ions serve as part of the alkaline reserve.
It is mostly transported as carboxy hemoglobin
As dissolved CO2
As bicarbonates
Due to CO2 molecules attached to hemoglobin
