B Lymphocyte Function:

  1. Recognition: B cells have surface antibodies that recognize specific antigens
  2. Activation: When antigen binds, B cell becomes activated
  3. Clonal Selection: Activated B cell divides rapidly
  4. Differentiation: Clone forms plasma cells and memory B cells
  5. Antibody Production: Plasma cells secrete thousands of antibodies per second

Quick Recall Flashcards

What is an antibody?
A Y-shaped protein (immunoglobulin) produced by plasma cells that binds specifically to antigens to neutralize or mark them for destruction.
What is an antigen?
A foreign substance that triggers an immune response by being recognized as non-self by the immune system.
