What is the primary function of neutrophils?

The primary function of neutrophils is to play a crucial role in fighting infections, particularly bacterial infections. Neutrophils are a type of white blood cell and are one of the first responders to sites of infection or inflammation. They can rapidly move to the affected tissues where they engage in phagocytosis, a process by which they engulf and digest microorganisms and foreign particles.

Neutrophils also release enzymes and react with reactive oxygen species to destroy pathogens. Their presence and activity are essential for the acute inflammatory response, contributing significantly to the body's innate immune defense. While other cells in the immune system, such as lymphocytes, are involved in producing antibodies and providing long-term immunity, neutrophils act quickly and are pivotal in the initial defense against infections.
