I need help with this please!

Organ transplantation can be used to replace injured or diseased organs such as the skin, heart, lungs, liver, kidneys, or pancreas. Any one of these transplantations can help a patient survive as long as your immune system does not step-in and reject them. There are two types of adaptive immunity: cell-mediated and antibody-mediated immunity. Both types can mount an attack against organ transplantation causing graft rejection.
