Function of kidney

The kidneys are a pair of organs which is bean shaped and located in the back of the abdomen. Each kidney is about 4 or 5 inches long -- about the size of a fist.The function of kidney is to filter the blood and it remove the waste material in the blood. Normally human beings have a pair of kidney but a very few people having one kidney due to some hereditary problems. In a day the blood passes through the kidney several time to get purified. Each kidney contains around a million units called nephrons. As we are having two kidneys if suppose one fails to do the function properly the another one works. If both are not functioning properly the person may die. This is due to blood pressure and stone(solid particle) formation in the kidney.
