  1. Autograft

  2. Isograft

  3. Xenograft

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

An autograft involves transferring tissue from one site to another within the same individual, ensuring genetic identity and preventing rejection. Isografts occur between genetically identical individuals, while xenografts occur between different species.

A Correct answer
Explanation

A- Allograft or allotransplant is the transplant of cells, tissues, or organs to a recipient from a genetically non-identical donor of same species. Most of the organ or tissue transplants in human are allografts.

Graft recognizes the recipient as foreign which can be seen in

  1. Transplantation rejection.

  2. Graft versus host disease.

  3. Passive immunization.

  4. Both A and B.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Graft versus host disease is a condition that might occur after an allogeneic transplant. In this, the donated bone marrow or peripheral blood stem cells view the recipient's body as foreign, and thus attack the body. 
So, the correct answer is option B.

Graft versus host disease mostly occurs after 

  1. Xenograft transplant.

  2. Allogenic transplant.

  3. Isograft transplant.

  4. None of the above.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Graft versus host disease (GVHD) occurs when immunocompetent cells from a donor graft recognize the recipient's tissues as foreign. This is most common in allogenic transplants where the donor and recipient are not genetically identical.

The graft rejection takes place due to the presence of ________

  1. T cells

  2. B cells

  3. Mast cells

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Graft rejection is primarily a cell-mediated immune response where T cells recognize foreign MHC molecules on the transplanted tissue. While other cells participate, T cells are the primary effectors of the rejection process.
