An organ transplant is a medical procedure where a healthy organ from a donor is placed into a recipient whose organ has failed or is damaged. This can involve various organs, such as the heart, kidneys, liver, or lungs. The goal is to restore normal function and improve the recipient's quality of life. Donors can be living or deceased, and matching the donor's organ with the recipient's body is crucial to reduce the risk of rejection. After the transplant, recipients typically need to take immunosuppressive medications to help their body accept the new organ and prevent it from being attacked by the immune system.
