Type of blood cell-
▪Red blood cells – Erythrocytes
▪White blood cells – Leukocytes
▪Platelets – Thrombocytes.

☆ White blood cells – Leukocytesp

cells of the immune system involved in defending the body against both infectious disease and foreign materials. Five diverse types of leukocytes exist, and are all produced and derived from multipotent cells in the bone marrow known as a hematopoietic stem cells. They live for about 3 to 4 days in the average human body. Leukocytes are found throughout the body, including the blood and lymphatic system.
The two main categories of white blood cells are granulocytes and agranulocytes.
Neutrophils (a type of granulocyte) are the most abundant of all the WBCs. Other cells included in granulocytes are eosinophils and basophils. Neutrophils are also called polymorphonuclear cells. It's nucleus is S-shaped. This cells are active phagocytes. It's abundance is 40-70% of total WBCs. Eosinophils are also called acidophils. It's nucleus is bilobed.It kills microbes and inactive some inflammatory chemicals. It's abundance is 1-4% of total WBCs. Basophils nucleus is multilobed.This cells play significant role in allergic reactions. It's abundance is 0-1% of total WBCs.

The five classes of leukocytes are:

neutrophils (40% - 75%)
eosinophils (1% - 6%)
basophils (less than 1%)
monocytes (2%-10%)
lymphocytes (20%-45%)
