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
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.
5- Define agglutination and specify its importance in blood grouping.
6- Note that for a blood transfusion to be successful or compatible, the recipient’s antibodies should not agglutinate with the donor’s antigens.
7- Compare the ABO system and the Rhesus System.
8- Is it possible to determine the blood group of a person by identifying his serum agglutinins? Justify.
9- Define antigen and list its different types.
10-Define pathogenic agents and give some examples.
11-Realize that the immune system can not differentiate between harmful and harmless substances; it only recognizes and fights the non self in healthy individuals.
12-Describe the formation of a modified self which is then attacked by the body’s immune system.
13-Differentiate between the different leukocytes populations and state their characteristics and role.
14-Name the primary lymphoid organs and the secondary lymphoid organs, then state the role of each.
15-Describe the steps of the maturation of (B and T) lymphocytes, and then state its importance.
16-State the structural and functional characteristics of Immunoglobulins(antibodies).
17-What is the significance of the constant and variable regions of an antibody?
18-Define antigen determinant or epitope, cross reaction, Immune complex and agglutination.
19- Explain how a B lymphocyte, TH lymphocyte, and TC lymphocyte recognize antigens or antigenic peptide.
