Hint: Diapedesis is a mechanism in which WBC comes out through the capillary wall in order to fight against foreign microorganisms.
Complete Answer:
A) Diapedesis is explained as the squeezing movement of WBCs at the site of infection. It is defined as the passage of blood, or any of its formed elements, through the intact blood vessels walls.
B) White blood cells (WBCs) or leukocytes are the cells present in the body that are involved in protection against both infectious diseases as well as foreign invaders.
C) All white blood cells are produced and derived from the multipotent cells present withinside the bone marrow which can be called hematopoietic stem cells. Leukocytes are formed at some stage in the body, inclusive of the blood and lymphatic system.
Additional information:
When a tissue has wound, germs from the exposed tissue are removed by the process of phagocytosis. WBCs start to accumulate at the site of wound by diapedesis, which is the movement of leukocytes to the site of infection by squeezing out through the endothelium of capillaries in order to fight against the foreign agent.
Note: Leukocyte extravasation is also called Diapedesis which is a characteristic of monocytes. Diapedesis is the motion of leukocytes out from the circulatory system closer to the tissues at the site of harm or infection.
