Explain the methods of i) Oxygen supply to the cells ii) Release of carbondioxide to the atmopshere from the cells during the process of transportation in humans.

Explanation

i) 97% of oxygen is taken in the form of oxyhaemoglobin by hemoglobin pigment present in RBC of the blood from lungs to various parts and 3% of oxygen is transported in dissolved form in blood plasma. ii) As carbondioxide is more soluble in water than oxygen, it is mostly transported in the dissolved form in blood plasma.
