Coloured SEM of a neutrophil white blood cell. Photography. Encyclopædia Britannica ImageQuest. Web. 25 Apr 2016.


Coloured Scanning Electron Micrograph (SEM) of a neutrophil white blood cell, seen on the endothelial surface of a vein (pink). The rounded neutrophil cell has microvilli projections which may assist the mobility of the cell. Neutrophils are the most common type of leucocyte (white cell) in blood, constituting 40-70% of all circulating leucocytes. They are formed in the bone marrow and use the blood as a transport system to reach sites of infection in the tissues. Neutrophils are very mobile and engulf and destroy cell debris and invading micro-organisms by the process of phagocytosis. Dead neutrophils occur in pus. Magnification: x6,090 at 6x7cm size. Magnification: x20,000 at 8x10 inch size.
