Neutrophil

Neutrophils are one of the most common types of white blood cell in mammals. They are capable of phagocytosis, the absorbance and destruction of foreign bodies to allow them to slow infection.

 

They are also known as polymorphonuclear leukocytes due to their distinctive segmented nuclei. Neutrophils are the first cells that migrate to the site of inflammation and are the predominant cells in pus. Neutrophils migrate up chemotactic gradients towards the site of inflammation. Cell surface receptors detect the relative concentrations of chemotactic agents and polarise the cell to migrate in that direction.
