What is a polymorphonuclear leukocyte?

polymorphonuclear leukocyte is a type of white blood cell, with "leuko", which means "white" and "cyte", which means "cell". The polymorphonuclear name comes from the common appearance of the cell nucleus, which seems to be many cores stuck together. The polymorphonuclear leukocyte is also known as granulocyte due to the granular nature of the cell cytoplasm. These are basophils, neutrophils and eosinophils. These cell types are named for their dye properties when the cells are colored, so they can be easily seen under the microscope. Basophils are colored by basophilic spots and eosinophils are easily colored with chemicals called eosin. Neutrophils do not occupy neither acidic nor basic stains particularly well, and therefore they are identifiable by a mild staining of both types.

polymorphonuclear leukocytes, which make up around 70 percent of all white blood cells, are, are, are, are around 70 percent of all white blood cells, are, produced in the bone marrow as part of the immune system. Cells that make cells are calledMyeloblasts. Polymorphonuclear leukocytes pass through the stages of growth when they are called myelocytes and metamyelocytes before they become leukocytes. Cells in these early stages do not respond in the same way to dyeing as more advanced cells, and they can also be recognized differences in the nuclear structure.

neutrophils make up about 60 percent of white blood cells and are about twice the size of red blood cells. Neutrophils contain lysosomal enzymes in their cellular granules. Lysosomal enzymes are substances that break down bacterial cells. When the immune system begins with the process of inflammation in the fight against infections, neutrophils move from the bloodstream to the affected area. There they collect and recognize bacteria with antibodies to which the immune system combines as marker for destruction.

eosinophils are less common than neutrophils and make up less than 6 percent of white blood cells found in the blood riverČiště. Their function is not well known, but it multiplies in response to parasite infection or allergic reactions. Basophils are even less common than eosinophils, which make up less than 1 percent of white blood cells. Their function is to trigger the process of inflammation in a similar role to tissue caustic cells. Basophils, eosinophils and neutrophils are approximately the same size.

Despite the name of the polymorphonuclear leukocyte cells, the multi-alcohol core does not necessarily contain at all times. Unripe neutrophils have a zone -shaped core and eosinophils, and basophils can also have band -shaped cores. Eosinophils can also have only two lobes on their core.
