The blood consists of a suspension of special cells in a liquid called plasma. In an adult man, the blood is about 1/12th of the body weight and this corresponds to 5-6 litres. Blood consists of 55 % plasma, and 45 % by cells called formed elements. The blood performs a lot of important functions. By means of the hemoglobin contained in the erythrocytes, it carries oxygen to the tissues and collects the carbon dioxide (CO2).
C. THE ROLE OF BLOOD IN EXCRETION. The wastes of excretion leave body cells and are secreted into intercellular fluid. Wastes pass from intercellular fluid into the blood plasma by the process of diffusion. The blood plasma transports these excretions to excretory organs that remove them from the body.he wastes of excretion leave body cells and are secreted into intercellular fluid.
