Organ donation is giving an organ to help someone who needs a transplant. Kidneys, heart, liver, lungs, pancreas and the small bowel can all be transplanted. Transplants are one of the biggest achievements of modern medicine and can save or greatly enhance the lives of other people. However, they depend completely on donors and their families consenting to organ or tissue donation. One donor can save the life of several people, restore the sight of two others and improve the quality of life of many more.
