IMMUNOLOGY

Detailed explanation-1: -Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).

Detailed explanation-2: -White blood cells, or leukocytes (Greek; leucko=white and cyte = cell), are part of the immune system participating in both the innate and humoral immune responses. They circulate in the blood and mount inflammatory and cellular responses to injury or pathogens.

Detailed explanation-3: -They help the body fight infection and other diseases. Types of leukocytes are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells). Checking the number of leukocytes in the blood is usually part of a complete blood cell (CBC) test.

Detailed explanation-4: -The white blood cells are called leukocytes (from the Greek “leukos” meaning “white” and “kytos, ‘’ meaning “cell”). The granular leukocytes (eosinophils, neutrophils, and basophils) are named for the granules in their cytoplasm; the agranular leukocytes (monocytes and lymphocytes) lack cytoplasmic granules.

Detailed explanation-5: -Normal Results The normal number of WBCs in the blood is 4, 500 to 11, 000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens.
