1. Definition

Neutrophils are a type of white blood cell (leukocyte) and belong to the granulocyte subclass, which contains granules filled with enzymes to destroy pathogens. They are the most abundant leukocytes, comprising 50-70% of all white blood cells in the bloodstream.

2. Functions

Neutrophils play a critical role in the innate immune system by being the first responders to sites of infection or injury.

Phagocytosis: Neutrophils engulf and digest pathogens through the release of digestive enzymes from their granules
Inflammation: They are key players in initiating the inflammatory response, which helps recruit more immune cells to the infection site
Rapid Response: Neutrophils are the first immune cells to migrate to areas of acute infection or trauma, providing an immediate defense

3. Physiology

Neutrophilia: Neutrophil count above 7,500 cells/µL.

Neutropenia: Neutrophil count below 1,500 cells/µL.
