A type of scavenging white blood cell involved in fighting infections that contains a segmented lobular nucleus and is colorless because of the lack of hemoglobin; eosinophils, basophils, and neutrophils are in this category.
The most numerous of the white blood cells (also known as neutrophil).
White blood cell that possesses a nucleus composed of 200 or more lobes or parts.
Formerly named microphages. Phagocytic (i.e., foreign particle-ingesting) white blood cells that have a lobed nucleus. For example, during an attack of the common cold (when virus first invades mucous membranes of the human nose), the body responds by making Interleukin-8 (IL-8); a glycoprotein that attracts large quantities of polymorphonuclear leukocytes to the mucous membranes of the nose (to try to combat the infection).
A white blood cell with a nucleus made of two or more lobes, i.e., the granular leukocytes: neutrophils, eosinophils, or basophils.
This particular white blood cell plays a crucial role in the body’s defense against infections, as its primary function is to eliminate any encountered pathogens. Interestingly, the leukocytes themselves suffer harm during their battle against these germs, and when we observe pus in a wound, it essentially consists of a multitude of deceased germs and white blood cells.
