Question

Name different types of WBCs

Answer 1

Hint: White blood cells are also called leukocytes. They are the immune cells that help in protecting from the disease by killing the pathogens when they enter into the body. Hence they are known as the police force of the body. They follow the process of phagocytosis to kill pathogens.

Complete Answer:
The three significant divisions of the white blood cells are granulocytes, monocytes and lymphocytes. The granulocytes are again classified into three distinct types as neutrophils, eosinophils and basophils.
- Granulocytes are phagocytes that can ingest unfamiliar cells, for example, microorganisms, infections and different parasites. Most of the white blood cells are granulocytes in nature. (I) Every neutrophil cell can invest up to between around five to twenty microscopic organisms in the course of its life.
(II) Eosinophils are associated with hypersensitive responses and can kill multicellular parasites, for example, worms.
(III) Basophils are engaged in the allergic responses and can deliver histamine and the hepari, which keeps blood from clotting.

- Monocytes can form into two sorts of cells as dendritic cells and the macrophages. Dendritic cells are antigen-introducing cells which can stamp out the antigens that should be devastated by lymphocytes. Macrophages are phagocytic cells which are bigger and live longer than neutrophils. Macrophages are additionally ready to go about as antigen-introducing cells.

- Lymphocytes are cells which help to manage the body's safe framework. They are either B or T lymphocytes. B cells help in delivering antibodies that attach to the antigens. Antibodies can either kill the objective organism or can check it out for assault by T lymphocytes.

Note: All the white blood cells are produced in the bone marrow only. The B lymphocytes produce in the spleen and the bone marrow and mature there itself. The T lymphocytes produce in the bone marrow and mature in the thymus gland.
