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. Transplants can come from living donors or deceased donors, and they are often necessary for patients with conditions like kidney disease or heart failure. Before a transplant, patients undergo evaluations to determine their suitability for the procedure. After receiving a transplant, recipients must take medications to prevent their bodies from rejecting the new organ. Successful transplants can significantly improve the quality of life and increase the lifespan of patients.
