Why does organ rejection occur?

Organ Transplant, SVCMC; New York NY
Your body has a natural defense system called the immune system that protects you from infection and disease. The immune system defends your body by producing "killer" cells that destroy foreign substances (such as viruses and bacteria). Since the donor organ doesn't match your old organ exactly, your body tries to destroy the transplanted organ. Essentially, a transplant creates a new disease called rejection. Rejection is nature's way of protecting your body.

Body Piercing, Jewellery Frequently Asked Questions | Flux P...
Rejection happens when you place a foreign object in your body (i.e. body jewellery) and your body, for one reason or another, considers that foreign object a threat to your health and safety. In order to protect itself, your body slowly fights the object by pushing it and healing the skin behind it to eventually force the object completely out through the skin. The process of the movement that slowly brings your body jewellery closer and closer to the skin's surface is migration.
