Functions and Constituents. Functions of blood. Transports gases, nutrients, waste, cells and hormones throughout the body. Transports O2, CO2, nutrients, hormones, heat and wastes. Regulates pH, temperature, water content of cells. Protects against blood loss through clotting. Protects against disease through phagocytic white blood cells and antibodies. The process by which blood is made is called Haemopoiesis. Blood Constituents. Blood consists of blood cells and plasma. If blood is treated with an anticoagulant and centrifuged, the blood cells sediment leaving a supernatant of clear plasma. Blood Cells. The sedimented blood cells account for 35-50% of the volume of blood and are of three basic types. 1  erythrocytes or red blood cells. 2  leucocytes or white blood cells. 3  platelets or thrombocytes.
