What Is a Polymorphonuclear Leukocyte?
Polymorphonuclear leukocytes, mainly neutrophils, include a small number of eosinophils and basophils. Also known as granulocytes. A type of white blood cell with segmented nuclei and a large amount of lysosome particles in the cytoplasm. The shape is small (10-15 m in diameter); the exercise force is strong (40 m / min), formed in the bone marrow, the life span is short (half-life is 6-7 hours), and it exists in the bloodstream and bone marrow. The lysosome contains bactericidal substances and enzymes, such as catalase, lysozyme, protease, phosphatase, nuclease and lipase.

They can penetrate the walls of blood vessels and exert their phagocytosis. [1]
- Having lobulated nuclei and granular cytoplasm
- There are three types of polymorphonuclear leukocytes: neutrophils, basophils, and eosinophils (ie, eosinophils). Among them, neutrophils are the most important because they account for three types of 90% of the cells account for 40% to 75% of the total number of white blood cells, and the content in human blood is 2500-7500 cells / mm 3 .
