Detailed explanation-1: -There are three means by which carbon dioxide is transported in the bloodstream from peripheral tissues and back to the lungs: (1) dissolved gas, (2) bicarbonate, and (3) carbaminohemoglobin bound to hemoglobin (and other proteins).
Detailed explanation-2: -Introduction. The hemoglobin (Hb) molecule within the red blood cell (RBC) carries oxygen from the lungs to the tissues, transports carbon dioxide from tissues back to lungs, and helps maintain acid–base balance.
Detailed explanation-3: -The blood transports oxygen from the lungs to the cells of the body, where it is needed for metabolism. The carbon dioxide produced during metabolism is carried back to the lungs by the blood, where it is then exhaled (breathed out).
