Question

Q.23 Describe various types of granulocytes.​

Answer 1

Answer:

The specific types of granulocytes are neutrophils, eosinophils, and basophils

Answer 2

1. Basophils are white blood cells that fight infection.

• It is the least prevalent form of granulocyte, accounting for just around 0.5 percent of circulating blood leukocytes.
• It serves a variety of functions, including CD4+ cell activation and differentiation, antigen presentation, and so on.
• Their nucleus is lobed, with two lobes connected by thin chromatin filaments.

Eosinophils are a kind of white blood cell that produces a substance called

• Nearly 1% of all circulating leukocytes are from this group. In immunological responses and the pathophysiology of autoimmune and allergy disorders, these structures play a variety of roles.
• Due to their proclivity to degranulate in the circulation, their granule count might fluctuate.
• Their nucleus is lobed and has a kidney shape.
• Their granules contain a one-of-a-kind protein that is essential for parasite elimination.

Neutrophils, number three.

• These are the most common leukocytes in humans' bodies, despite the fact that there are many additional varieties.
• It serves as the body's first line of defence against infection.
• These phagocytes make up 60-65 percent of all circulating white blood cells and can be found throughout the body.
• Neutrophil-killers and neutrophil-cagers are the two components of these cells.
• Neutrophils leave the circulation to travel to the infection location after getting appropriate signals.

Mast cells, number four.

• These granulocytes can be detected in tissues with a lot of histamine and heparin in the granules.
• Their involvement is critical in immunological tolerance, allergies, and pathogen response (parasites, for example).
• They regulate and modulate neuroimmune system responses as well as mediate autoimmunity and inflammation.
