Question
1.Compare a primary and a secondary immune response. Answer should mention speed of onset, magnitude of increase in antibody titer and main class of antibody involved.
2. Of plasma, interstitial fluid and lymph, which is most unlike the other two? Describe the major difference?
3. a)Several genetic disorders can lead to infants being infants being born lacking a functional thymus. Which component(s) of the normal immune response would be missing in these individuals?
b) What would be the primary consequence of this lack?
Explanation / Answer
Question 1
Answer
Immunity is natural protection of the body against foreign bidy. These are primary immune response and secondary immune response.
Primary immune response;
1. It is developed when contacted with foreign body or antigen.
2. The maximum level of antibodies reaches more than 7 days.
3. The lag phase is inbetween 5-7 days.
4. The first antibody produced is IgM and followed by IgG antibody.
5. The B cells and The cells are responded.
6. The level of antibodies decline rapidly.
7.the affinity of antibody to antigen is less.
8. It mainly occurs in the lymph nodes and spleen.
9. Its establishment takes longer time.
Secodary immune response ;
1. It occurs on second exposure to same type of antigen.
2. It has memory cells and those produce response.
3. The lag phase is 1-4days and it is lesser than primary response because of memory cells.
4. The maximum level of antibodies reaches in 1-5 days.
5. Here the main antibody produced is IgG. Other antibodies in small quantities is IgM, IgM and IgE.
6. Its establishment take less time.
7. 100 to1000 more antibodies are produced compared to primary response.
8.they last for longer period
9. It mainly occurs in bone marrow. Other are spleen and lymph node.
