Best Answer

To transport oxygen (oxyhaemoglobin) and glucose to respiring cells in order to produce energy for bodily functions. It also transports hormones around the body to various organs. The blood also contains white blood cells which can be transported to areas of the body which may be being attacked by harmful bacteria or viruses. It also contains platelets which help the blood to clot should you get a cut. All of these substances are suspended in a substance called plasma, which makes up the majority of blood.
