D) blood cells

Question

Quizplus · Accepted Answer

Natural killer cells are a type of lymphocyte that belongs to the innate immune system. They are able to recognize infected cells without the need for prior exposure or stimulation, and can non-specifically kill these cells through the release of toxic granules. Phagocytic cells, on the other hand, engulf and digest foreign particles including microbes, but do not specifically target infected cells. Memory cells are a type of T or B cell that remain in circulation after an initial infection, allowing for a quicker and more efficient response to subsequent infections. Blood cells refer to any cell found in the blood, including red blood cells, white blood cells, and platelets, but do not specifically relate to cells that kill infected cells.
