Answer 1

Antigen

1 Generally proteins but can be lipids, carbohydrates or nucleic acids.

2 Triggers the formation of antibodies.

3 There are three basic kinds of antigens. (Exogenous, Endogenous and Autoantigens)

4 The region of the antigen that interacts with the antibodies is called epitopes.

5 Cause disease or allergic reactions.




Antibody
1 Antibodies are proteins.

2 Variable sites has the antigen binding domain.

3 There are five basic kinds of antibodies. (Immunoglobulins M, G, E, D and A)

4 The variable region of the antibody that specially binds to an epitope is called paratope.

5 Protects the body by immobilization or lysis of antigenic material.


Blood transfusion

1 Blood transfusions can be a life saving measure.

2 Volunteer donor blood usually is readily available, and when properly tested has a low incidence of adverse events.

3 The likelihood of contracting infections from a blood transfusion is very low (varies with the infectious agent from 1 in 350,000 to 1 in 1 million), but can occur.

4 Transfusion of your own blood (autologous) is the safest method, but requires planning and not all patients are eligible. It is usually only an option for elective surgery.

5 Directed donor blood allows the patient to receive blood from known donors.
