Which statement about gas (O2 and CO2) transport in humans is correct?

Question

(a) Most carbon dioxide is transported bound to hemoglobin (b) Oxygen combines with water in the blood to form bicarbonate ions (c) In the systemic circulation (blood going to supply the body cells) oxygen diffuses from the cells into the capillaries, and carbon dioxide diffuses from the capillaries into the cells (d) Most oxygen is transported bound to hemoglobin (e) The concentration of oxygen is higher in venous blood than in arterial blood

Answer 1

Oxygen is transported to all the cells through blood circulation and blood carries the oxygen to cells in the form of "Oxyhemoglobin": that is the hemoglobin molecule bound with oxygen molecules. 

 

 

Hope you get the point and it is clear, if not then please let me know.
