Functions of blood are as follows:
-It transports nutrients after digestion and absorption to each cell of the body
-Waste from all parts of the body is carried by the blood to the organs that remove this waste
-It transports oxygen from lungs to all the tissues and brings back carbon dioxide from the tissues to the lungs
-It protects the body against disease-carrying germs by digesting and destroying them
-Chemical messengers called hormones and enzymes are transported by the blood
-It helps to maintain constant body temperature.This is because by constant circulation, the heat produced in our tissues gets distributed.
