topic: sec. 9.4
skill: knowledge

Explanation:

In the immune - response, when chemicals are released from injured cells, it triggers the release of histamine from mast cells. Mast cells play a key role in the inflammatory response by releasing histamine which causes blood vessels to dilate and become more permeable. Macrophages are phagocytic cells that mainly function in engulfing and digesting pathogens and debris, not in histamine release in response to injured - cell chemicals.

Answer:

mast cells
