Question

Quizplus · Accepted Answer

Phagocytes serve two functions in immune responses. The first is to engulf and destroy foreign cells, such as bacteria and viruses. The second is to alert the other cells of the immune system to the invader by presenting them with pieces of the destroyed pathogen. This alerts other immune cells to the presence of the invader and helps coordinate the overall immune response. Production of antibodies is not a function of phagocytes, and while they can serve as a physical barrier against microbial invasion, this is not one of their main functions in immune responses.
