♥ Transport of oxygen - Haemoglobin present in the blood takes up the oxygen from the air in the lungs . It carries the oxygen to tissues which are deficient in oxygen before releasing it .

dioxide is more soluble in water .
Therefore , it is mostly transported from
body tissues in the dissolved form in our
blood plasma to lungs . It diffuses from
blood to air in the lungs .
