In a healthy,functioning immune system,________ search out and destroy cancer cells.

Question

Quizplus · Accepted Answer

NK cells (Natural Killer cells) are a type of lymphocyte (a type of immune cell) that has the ability to recognize and destroy cancer cells, as well as other infected or abnormal cells in the body. Carcinogens are substances that can cause cancer, but they do not actively search out and destroy cancer cells. B lymphocytes produce antibodies and play a role in fighting infections, but they do not have the same direct role in recognizing and destroying cancer cells as NK cells. Endorphins are hormones that are associated with feelings of pleasure and pain relief, but they do not play a role in the immune system's response to cancer.
