| Component of Blood | Quantity | Description | Functions |
| Blood plasma 1) Water 2) Plasma proteins Albumin Globulins Fibrinogen 3) other solutes Electrolytes Nutrients Gases Regulatory substances Waste products | 55% 91.5% of total blood plasma 7% (albumin, globulin and fibrinogen) of total blood plasma 54% of total plasma protein 38% of total plasma protein 7% of total plasma protein 1.5% of total blood plasma | Liquid portion Mostly produced from liver Small in size and most numerous protein Large in size Plasma cells produce immunoglobulins (Ig) Large in size Inorganic salt: Cation: Na+, Mg++, K+, Ca++, Anion: Cl-, HPO4--, SO4- - Amino acids, glucose, vitamins and minerals Oxygen Carbon di oxide Nitrogen Hormone Enzyme Vitamins Urea, creatinine, uric acid, ammonia, bilirubin | Transport, absorb and release heat Solvent medium Transport fatty acids, hormones and calcium. Help to maintain blood pH. Regulate blood viscosity, Ig help attack by virus and bacteria Help to transport fat soluble vitamins, lipid and iron. Play vital role in blood clotting mechanism Help to regulate osmotic pressure Essential for cell growth and development O2 is important for many cellular functions Involved in regulation of blood pH -- Regulate growth, development and metabolism. Catalyze reaction Enzymatic reaction Most are breakdown products, and carried by blood to excretion organ |
