Neutrophils _______

Question

Neutrophils _______.
A) release clotting factors
B) release histamine in injured tissue
C) are the main phagocytes in the blood
D) can develop into macrophages

Accepted Answer

Neutrophils are the main phagocytes in the blood, meaning they are specialized cells that engulf and destroy invading pathogens. While other white blood cells may also have phagocytic abilities, neutrophils make up the bulk of the body's innate immune response and are particularly efficient at eliminating bacteria. A is incorrect because clotting factors are mainly released by platelets. B is incorrect because histamine is primarily released by mast cells and basophils during an allergic response. D is incorrect because while some macrophages may arise from monocytes (another type of white blood cell), neutrophils do not differentiate into macrophages.
