If your body senses a foreign object it will try to reject it. So any transplant is viewed as a foreign object. Doctors give you anti rejection medication but this does not always work so the body rejects the transplant. Other reasons are that the operation in general just failed or the transplanted organ itself failed rather than being rejected as a foreign object.
Organ and Tissue transplant patients can sometimes go through rejection because the immune system may identify foreign substances which can Carrie proteins called antigens that may be potenially harmful. The immune system will then attack those substances therefore leading to a rejection.

If you mean social rejection, then it is due to religious stigmatism. Several religious groups believe that it is wrong to receive transplants from other people because it is 'playing God'. Personally I feel that if there really is a God - who made everything in the universe - then he is responsible for the creation of the possibility for transplants, similar to how he is responsible for giving lions the instinct to kill.
Therefore, I feel that it is one's right to receive transplant. But anyway, this is not about me. I guess it just comes down to religion, and how some people socially reject others because they are not obeying other people's religious views.
i think it is because they have a different blood type that wont work in their body
Rejection occurs when the transplanted organ, or in this case, tissue, is not accepted by the body. The immune system recognizes the organ or tissue to be a foreign substance and attacks it in an attempt to kill it.
It is not the organ that rejects the patient's body, it is the patient's body that rejects the organ.
The patient's immune system can tell that the organ is made up of different DNA to the rest of it's body, hence attacks it with T-lymphocytes (a type of white blood cell). (This is similar to how the human body fights off the 'flu virus, which has it's own special type of DNA). The process of attacking the transplanted organ is called rejection. The new DNA from the transplanted organ is perceived as a 'threat' by the immune system; rejection is a natural response to the presence of a "foreign body" within the patient's body. It's just not a useful response, in this instance.

Why are pigs organs rejected in human bodies?
Tissue rejection occurs because the body does not recognize the tissue as compatible. This can be because the proteins are different for example.
Which class of tissue graft is the least likely to be accepted by a patient's body?
Xenografts, which are tissue grafts taken from a different species, are typically the least likely to be accepted by a patient's body due to immune system rejection. This rejection occurs because the patient's immune system recognizes the xenograft as foreign tissue and mounts an immune response against it.
How often does rejection occur in liver transplantations?

Growth occurs when what is made?

Is a malignant tumor that occur in epithelial tissue?
A carcinoma is a malignant tumor that occurs in epithelial tissue.
Transplanted organs may be rejected in the type of immune response called?
Rejection of transplanted organs occurs in the type of immune response called "graft rejection". This occurs when the recipient's immune system recognizes the transplanted organ as foreign and attacks it, leading to potential organ failure. Medications are often used to suppress this immune response and prevent rejection.
