Question

multiple choice question
what are monocytes that migrate to the tissue and function as phagocytes called?

macrophages
plasma cells
nk cells
t cells
b cells

Explanation:

To solve this, we recall cell biology concepts: Monocytes are white blood cells. When they migrate into tissues, they differentiate into macrophages, which are phagocytic cells (they engulf and digest pathogens, debris). Plasma cells are differentiated B cells for antibody production. NK cells (natural killer cells) are for immune surveillance. T cells and B cells are lymphocytes involved in adaptive immunity, not derived from monocytes as phagocytes. So the correct option is Macrophages.

Answer:

A. Macrophages
