Cell Quizzes & Trivia

T cells come in different forms there are those T-cells that hunt down and destroy cells that are infected with germs the other main type of T-cells are orchestrate an immune response. Antigens are any substance that stimulates the immune system to produce antibodies. Take up the quiz below and learn more about these.
