Kidney Transplant-Homeostasis:

Definition:

A kidney transplant is a surgical procedure to place a kidney from a live or deceased donor into a person whose kidneys have no longer function properly.

Explaination:

Your kidneys remove excess fluid and waste from your blood. When your kidneys lose their filtering ability, dangerous levels of fluid and waste accumulate in your body — a condition known as kidney failure or end-stage kidney disease. A kidney transplant is often the best treatment for kidney failure.

Only one donated kidney is needed to replace two failed kidneys, making living-donor kidney transplantation an option.
