Organ transplant is a medical procedure in which an organ is removed from one person (or animal) and surgically placed into another person in order to replace a failing or damaged organ. This procedure is commonly used to treat end-stage organ diseases such as heart, kidney, liver, and lung failure. Organ transplant can dramatically improve the quality of life and increase the chances of survival for patients with organ failure. However, organ transplantation also comes with risks such as rejection, infection, and complications from immunosuppressant drugs. Researchers in the field of organ transplant are constantly working to improve transplant success rates, increase organ availability, and develop new technologies to enhance the transplant process.
