E. B cells - ANSWER: C. Cytotoxic T cells (CD8 cells)
Which of the following statements regarding phagocytes and phagocytosis is true?
A. Macrophages, monocytes, and mast cells are phagocytes.
B. Contact of phagocytes with microbes stimulates the phagocytes to release chemicals that mediate
the inflammatory response.
