what are the roles of white blood cells in tissue rejection?
Answers
Answer:
Function of White Blood Cells White blood cells are a part of your immune system that protects your body from infection These cells circulate through your bloodstream and tissues to respond to injury or illness by attacking any unknown organisms that enter your body
Answer: White blood cells recognize the body's tissues by looking for a set of antigens on the surface of each cell. In hyperacute rejection, the body immediately begins to fight off the foreign tissue, and symptoms appear almost immediately after the operation. Graft rejection occurs when the recipient's immune system attacks the donated graft and begins destroying the transplanted tissue or organ. The immune response is usually triggered by the presence of the donor's own unique set of HLA proteins, which the recipient's immune system will identify as foreign.
