Background

  • A neutrophil is a granulocyte (a type of white blood cell) that is designed to fight off infections and diseases that enter the body. Neutrophils, along with eosinophils and basophils, are members of the polymorphonuclear cells (PMNs).
  • These cells are filled with neutrally-staining granules, which are small pouches of enzymes that allow the cell to destroy an invading microorganism it has engulfed during phagocytosis.
  • Neutrophils are the most abundant type of white blood cells in the body, making up 70% of all leukocytes (white blood cells). These cells play an important role in the immune system. When a pathogen (disease-causing microorganism) enters the body, neutrophils are the first phagocytes to attack the invader.
  • These cells are the main component of pus, and are responsible for its yellow/white appearance.
