What is the main function of neutrophils?

Neutrophils are a type of white blood cell that play a crucial role in the innate immune response, primarily by engulfing and destroying pathogens. This process is known as phagocytosis, where neutrophils identify, ingest, and subsequently degrade bacteria and other foreign particles that invade the body. They are often one of the first responders to sites of infection or inflammation, rapidly arriving in response to signals from the immune system.

The primary function of neutrophils as phagocytes is vital for the initial defense against bacterial infections, preventing the spread of pathogens and aiding in the healing process. Their ability to move toward sites of infection through a process called chemotaxis further enhances their effectiveness in protecting the body from microbial threats. This makes their role in engulfing pathogens essential in the broader context of immune function and maintaining health.
