Neutrophils are a type of white blood cell that play a crucial role in the body's immune response. They are the most abundant type of leukocyte, making up about 60-70% of all white blood cells. Neutrophils are characterized by their multi-lobed nucleus, which can range from two to five lobes. They are produced in the bone marrow and are typically the first cells to arrive at sites of infection or injury.

Neutrophils are highly effective at phagocytosis, the process by which they engulf and destroy pathogens such as bacteria and fungi. They do this by releasing enzymes and reactive oxygen species that kill the invading microorganisms. Neutrophils also play a role in inflammation by releasing chemicals that attract other immune cells to the site of infection.

There are two main types of neutrophils: polymorphonuclear neutrophils (PMNs) and band neutrophils. PMNs are the most common type and are found in the bloodstream. Band neutrophils are less mature and are found in the bone marrow and tissues. They can quickly transform into PMNs when needed.

Neutrophils have a relatively short lifespan, typically lasting only a few days in the bloodstream. They are then replaced by other types of white blood cells. Neutrophils are essential for maintaining the body's defenses against infections, but an imbalance in their numbers or function can lead to various health issues, including infections and autoimmune disorders.
