Kidney are important organs for human.The main function of the kidneys is to get rid of waste products from our body that are created by the body's constant metabolism.

If a person gets Renal Failure, that is his/her has lost some renal functions. Kidney failure occurs when both the kidneys fail to function as desired and are not able to rid the body of these harmful toxins and excess fluid. The toxic blood and excess water in turn will cause many other complications, leading to severe ailments, at times fatal.
