It is a red coloured fluid. | It is a colourless fluid. |
Blood is opaque. | It is almost transparent. |
Water content is nearly 55%. | Water content is nearly 94%. |
Blood is quite viscous. Viscosity is about 4.7. | It is less viscous. Viscosity is less than 2.0. |
It consists of plasma, blood corpuscles, inorganic and organic substances. | It consists of plasma, lymphocytes and no erythrocytes and platelets. |
Part of the closed circulatory system. | Part of the open circulatory system. |
It is rich in proteins, calcium and phosphorous. | It has fewer proteins and less of calcium and phosphorous. |
Albumin:Globulin ratio is more than unity. | Albumin:Globulin ratio is low, 1:5. |
It starts from the heart and flows through arteries, capillaries and finally returns to the heart through veins. | It starts from tissue spaces and flows through lymph capillaries, lymph vessels and finally joins the subclavian veins by thoracic duct and right lymphatic duct. |
It distributes nutrients from one part of the body to another. So, it acts as a vehicle. | It transfers nutrients from the blood to the tissues and returns wastes from tissues to the blood. So, it acts as ‘middle man’. |
Blood flow is rapid. | Lymph flow is very slow. |
It contains a normal quantity of carbon-dioxide, metabolic wastes and less concentration of glucose. | It contains a sufficient amount of carbon-dioxide, metabolic wastes and a higher concentration of glucose. |
