The kidneys are the vital organ of the body located towards the lower back. The two kidneys help filter the blood and remove toxins from the body. The toxins that get filtered from the blood are sent to the bladder which is later on removed during urination.
Kidney failure occurs when the kidneys lose their function and become incapable of sifting the waste from the blood. Many factors can interfere with the kidney’s function and cause renal or kidney failure.
