Macrophages, Neutrophils, and Dendritic Cells

Question 2

These phagocytic cells are the first cell line of defense and are found in connective tissue that underlie epithelial tissue throughout the body. (Big Eaters).

Answer 2

macrophages

Question 3

These phagocytic cells travel to the nearest lymphatic organ to activate adaptive immunity by presenting antigen to the T cells.

Answer 3

dendritic cells

Question 4

These phagocytic cells only eat a few bacteria before they die but they are more numerous in the blood than any other WBC.They form Pus.
