Final answer:
Neutrophils function to phagocytize bacteria, being a key component of the immune response and inflammation by engulfing and destroying pathogens.
Step-by-step explanation:
The function of neutrophils is to phagocytize bacteria. Neutrophils are a type of leukocyte, or white blood cell, that are the first to arrive at a site of infection. They play a critical role in the body's immune response by engulfing and destroying pathogens through phagocytosis. Neutrophils contain cytoplasmic granules which are filled with chemicals that can break apart pathogens. This action, combined with the ability to ingest bacteria, makes them essential components of the inflammatory response. Unlike mast cells and basophils, neutrophils do not typically release histamine. Instead, they release other chemicals that can stimulate inflammation and help to break down invading pathogens.
