The questions below will help you assess your knowledge about the basics of the Immune System… ENJOY finding the answers!!

Note: Two of the following items are not questions, they are hints to be kept in mind  Smile

1- Describe the characteristics of the genes, alleles and molecule types of the MHC or HLA molecules .

2- Define: Autograft, Isograft, Allograft and Xenograft.

3- Explain how the body decides to accept a graft (vascularization appears around it) or to reject it (redness-edema-black-dry).

4- State the types and location of Agglutinins  and the Agglutinogens found in each blood group of the human ABO system.

6- Note that for a blood transfusion to be successful or compatible, the recipient’s antibodies should not agglutinate with the donor’s antigens.

10-Define pathogenic agents and give some examples.
