18 Questions
During the establishment of immunity, which phase takes a longer time?
Lag phase
Which antibody is mainly produced during the primary immune response?
IgM
What happens to antibody levels after the primary immune response?
Antibody level declines rapidly
Which antibody has the greatest affinity for the antigen?
IgG
Where does the secondary immune response primarily appear?
Bone marrow, spleen, and lymph nodes
Which type of antigen triggers the secondary immune response?
Only Thymus-dependent antigen
What characterizes the lag phase of antibody production?
Stabilization of antibody levels
Which phase involves the largest number of plasma cells?
Exponential Phase
In which phase does antibody degradation exceed synthesis?
Decline Phase
What happens during the plateau phase of antibody production?
Constant antibody levels due to equal synthesis and degradation rates
Which immune response involves the activation of B-cells?
Primary B-cell Response
What causes the decrease in antibody levels during the decline phase?
Exhaustion of antibody production by plasma cells
What is the main reason for the shorter Lag phase in responding cells?
Presence of memory cells
During which phase does the level of antibody production reach its peak faster?
Exponential phase (3-5 days)
Which immunoglobulin is primarily produced as the first antibody?
IgM
What is a characteristic of the antibody levels during the primary response compared to the secondary response?
Primary response has greater affinity for antigens
What determines the amount of antibody produced during an immune response?
Nature of antigen
Which phase is characterized by a rapid decline in antibody levels?
Decline phase
