Question

Quizplus · Accepted Answer

Neutrophils and macrophages are the two principal phagocytic cells that function in defense against disease. Neutrophils are the first responders to infection and are highly effective at killing invading organisms. Macrophages are larger cells that also phagocytose invading pathogens, and they play a crucial role in presenting antigens to the immune system. Other cells listed in the answer choices, such as T-cells and B-cells, also play important roles in the immune response, but they are not phagocytic cells.
