There is red-coloured pigment in the red blood cells called haemoglobin which increases the carrying capacity of the blood between 65 and 70 times. Each red blood cells contain about 250 million haemoglobin molecules. Oxygen concentration in cells is low i.e when leaving the lungs blood is 97% saturated with oxygen, so oxygen diffuses from the blood to the cells when it reaches the capillaries.
