Organ transplants are medical procedures where a healthy organ from a donor is placed into a recipient whose organ has failed or is damaged. Common organs that can be transplanted include the heart, kidneys, liver, and 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 prevent rejection. After the transplant, recipients usually take medications called immunosuppressants to help their bodies accept the new organ and reduce the risk of rejection.
