An organ transplant is a medical procedure where a healthy organ from a donor is placed into a patient 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 the patient's health and improve their 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, patients typically need to take medications, known as immunosuppressants, to help their bodies accept the new organ and prevent rejection.
