B-cells

• B-cells are a type of white blood cell
• B-cells are covered with antibodies
• antibodies are proteins which bind to antigens to form an antigen-antibody complex
• each antibody is specific to an antigen due to their different shapes
• 1. the antibody on the surface of the B-cell meets a complementary shaped antigen and binds to it
  2. this activates the B-cell, along with chemicals from helper T-cells, this is called clonal selection
  3. the activated B-cell divides into plasma cells
