Granulocyte

Granulocyte is a type of white blood cell that is filled with microscopic granules, tiny sacs that contain enzymes to digest microorganisms. Granulocytes are part of the immune system, and they help to fight off infections by bacteria and fungi. There are three types of granulocytes: neutrophils, eosinophils, and basophils, each with different functions.

Types of Granulocytes

Neutrophils

Neutrophils are the most common type of granulocyte. They are the first to arrive at the site of an infection. Neutrophils are capable of ingesting microorganisms and are essential in the defense against bacterial infections.

Eosinophils

Eosinophils are less common than neutrophils. They are responsible for combating multicellular parasites and certain infections in vertebrates. Eosinophils also control mechanisms associated with allergy and asthma.

Basophils

Basophils are the least common of the granulocytes. They can perform phagocytosis (ingesting microorganisms), produce histamine and serotonin that induce inflammation, and heparin that prevents clotting.

Function of Granulocytes

Granulocytes, like other white blood cells, play a crucial role in the immune response. They help to defend the body against harmful bacteria, viruses, and parasites. They do this by ingesting and destroying these harmful organisms, a process known as phagocytosis.

Granulocyte Disorders

There are several disorders associated with granulocytes. These include neutropenia, a condition characterized by low levels of neutrophils, and neutrophilia, which is an increase in the number of neutrophils. Other disorders include eosinophilia and basophilia, which involve high levels of eosinophils and basophils, respectively.
