Biological grafts are tissues or organs taken from one part of the body and transplanted to another, or from a donor to a recipient. They are used in various medical procedures to repair or replace damaged tissues, such as in surgeries for burns, wounds, or organ transplants. These grafts can be made from the patient's own tissue, known as autografts, or from a donor, called allografts. The success of biological grafts depends on factors like the compatibility of the tissues and the recipient's immune response. Proper care and monitoring are essential to prevent complications, such as rejection or infection. Advances in medical technology continue to improve the effectiveness of grafts in promoting healing and restoring function.
