Lymphocyte Animation

Lymphocytes consist of B-cells and T-cells. When a white blood “B-cell” encounters an antigen, or a foreign, potentially dangerous body, it secretes antibodies that attach to the antigen. This signals for cytotoxic T-cells to find and destroy the antigen. Interact with this simulation with the arrow keys and WASD to play as the B-cell. Try and tag as many bacteria as you can, and watch as they migrate to a location of the blood stream where they will be destroyed by the T-cells!
