Answer
Exam answer
NEUTROPHILS (also accepted: monocytes / macrophages).
Explanation
Phagocytosis is the engulfing and digesting of bacteria and other foreign particles. Neutrophils are the most numerous white cells and the first to reach a site of infection; monocytes, which become macrophages in the tissues, do the same on a larger scale.
The pus at an infected wound is largely dead neutrophils together with the bacteria they engulfed.
Neutrophils and monocytes are both GRANULOCYTE or phagocytic types — they attack directly, by swallowing.
