T Cell activation

T cell combines with B cell combined with the antignen, Helper T cell releases cytokines.

B cell proliferation

occurs after activation, and B cells proliferate rapidly.

B Cell Differentiation

Strength of secondary immune response

Stronger than primary immune response, due to memory B cells and memory T Cells

Antibody production, localized changes after antibody action, and where antibodies are found

Localized changes: inflammation, edema, antibody production, vasodilation
Antibodies found- plasma, tissue fluids, exocrine secretions, surfaces of B cells
