Immunologic Disorders Pedia

Question 1

major organ of the immune system

Answer 1

spleen

Question 2

Differentiate Antigen and Antibody

Answer 2

Antigen (outside of body)
- Toxin or foreign substance which induces an immune response in the body
Antibody
-produced in response to and counteracting a specific antigen

Question 3

Give the types of Antibody and their roles

Answer 3

IgA
- Found in mucous, saliva, tears and breast milk.
- Protects against pathogens

IgD
Part of the B cell receptor.
Activates basophils and mast cells

IgE
Protects against parasitic worms.
Responsible for allergic reactions

IgG
Secreted by plasma cells in the blood. Able to cross the placenta into the fetus

IgM
May be attached to the surface of a B cell or secreted into the blood.
Responsible for early stages of immunity

Type 3: Immune complex hypersensitivity
Type 4: cell mediated hypersensitivity

Question 11

Type I : Anaphylactic Hypersensitivity

Answer 11

caused by IgE characterized by Vasodilation, increased capillary permeability, smooth muscle contraction and eosinophilia.

Question 12

These are examples of what hypersensitivity reaction?

Answer 12

Type 1 Anaphylactic Hypersensitivity

Question 13

Type 2: Cytotoxic hypersensitivity

Answer 13

It occurs when the system mistakenly identifies a normal constituent of the body as foreign

Question 14

This reaction may be a result of cross-reacting antibody, possibly leading to cell and tissue damage
It involves activation of complement by IgG or IgM antibody binding to an antigenic cell
