Cells that release histamine during the inflammatory response
Cells that eat pathogens and destroy them
Cells in the immune system with four-part receptors shaped like a Y
Cells in the immune system with two chains
The Correct Answer is B
A. Cells that release histamine during the inflammatory response. Cells that release histamine during inflammation are mast cells, not phagocytic cells.
B. Cells that eat pathogens and destroy them. Phagocytic cells, such as macrophages and neutrophils, engulf and digest pathogens in a process called phagocytosis.
C. Cells in the immune system with four-part receptors shaped like a Y. Cells with Y-shaped receptors are B cells, which produce antibodies, not phagocytes.
