Which type of white blood cell is known for engaging in phagocytosis?

Neutrophils are a type of white blood cell that plays a crucial role in the immune response, particularly through the process of phagocytosis. Phagocytosis is the mechanism by which cells engulf and digest pathogens, dead cells, and other debris, helping to clear infections and maintain healthy tissue. Neutrophils are often the first responders to sites of infection or inflammation, rapidly moving to the affected area where they can identify and ingest harmful microorganisms.

Their ability to perform phagocytosis is enhanced by their numerous granules, which contain enzymes and antimicrobial substances that help to kill and digest the engulfed pathogens. This function is essential for the body's defense, especially in combating bacterial infections.

In contrast, eosinophils are primarily involved in responding to parasitic infections and mediating allergic reactions. Basophils are also involved in allergic responses and inflammation but do not play a significant role in phagocytosis. Lymphocytes, which include T cells and B cells, are primarily involved in the adaptive immune response, focusing on the recognition of specific pathogens and the coordination of the immune response rather than direct engulfment and digestion of pathogens.
