Question

Quizplus · Accepted Answer

Natural killer cells are a type of lymphocyte that can recognize and kill cells that are infected with viruses or have become cancerous. They do not require prior exposure to a specific antigen, making them part of the innate immune system. Perforins are proteins released by natural killer cells that create pores in the target cell's membrane, causing it to lyse. Platelets help with blood clotting, mucus helps to lubricate and protect surfaces, and antimicrobial proteins help to fight off infections.
