Answer» diagram of the human circulatory Why is it necessary to excrete waste products ? →The process of REMOVING waste products produced in the cells of living organisms is called excretion. Certain waste and toxic products are formed during the functioning of body cells. The waste products like urea etc. are toxic. When these toxic MATERIALS are not removed from the body, they get mixed with blood and can damage the cells of the body. Hence it is necessary to REMOVE such poisonous waste materials from our body. The kidneys are two bean-shaped EXCRETORY organs that remove these toxins from your blood and produce urine to carry them from the body. |
