Dustin Lee 31.3: Q 1-4 Block C: Biology 1. Every antibody comes in a specific shape. At the tip of each part of a shape is an antigen- binding site, or antigen receptor. The shape of this binding site makes it possible for the antibody to recognize a specific antigen with a complementary shape. 2. Both B and T cells travel in the blood to the lymph nodes and other parts of the lymphatic system. Both B and T cells are lymphocytes that are white blood cells that recognize specific invaders. 3. A second exposure to the same pathogen triggers a much quicker and stronger response

Unformatted text preview: called the secondary immune response. The second exposure stimulates the memory B cells to rapidly produce plasma cells that will secrete antibodies specific to that antigen. Meanwhile memory T cells rapidly produce large numbers of cytotoxic T cells that attack cells infected with the pathogen. The process is so quick that you don’t develop symptoms of the disease. 4. The altered membrane may alert T cells to an intruder in the body. Cytotoxic T cells then proceed to destroy the cancer cells....
