Discuss the composition and functions of mammalian blood

• Mammalian blood consists of two main components: Blood plasma  and blood cells; and the blood cells; (Red blood cell is Erythrocytes, White blood cells Leucocytes and Platelets Thrombocytes);
• Blood plasma transport nutrients (glucose, amino acids, vitamins, fatty acids and glycerol, dissolved oxygen) to tissues; 
• Blood transports hormones, enzymes, metabolic regulators to target organs and tissues; 
• Blood transports excretory substances wastes from the cells; to excretory organs for elimination from the body; 
• Blood distributes heat energy;  in thermoregulation; 
• Transported is water, plasma proteins and dissolved mineral salts; important in osmoregulation;
•  Blood suspends blood cells;
