B cell and humoral response - next phase of immunity

Question 1

Humoral response

Answer 1

Involves antibodies. Antigen enter B cell by endocytosis and presented on surface , T cell bind to these processed antigens activating B cells to divide via mitosis to make clones of plasma cells. Plasma cells secrete antibodies and specific antibody forms a antigen antigen antibody complex .

Question 2

What is the primary response

Answer 2

Production of antibodies/memory cells for first time. Very slow and happens when foreign antigen enters for the first time

Question 3

What is the secondary response

Answer 3

Memory cell recognizes the same antigen it divides rapidly to T cells and forms plasma cells provide long term immunity
