Neutrophils are a type of white blood cell that play a crucial role in the immune system. They are the body's first line of defense against infections, particularly bacterial infections. Neutrophils are produced in the bone marrow and are released into the bloodstream, where they can quickly respond to sites of infection or injury.
These cells work by engulfing and destroying pathogens through a process called phagocytosis. Neutrophils also release enzymes and chemicals that help to break down and eliminate harmful microorganisms. Their rapid response and ability to fight infections make them essential for maintaining overall health.
