MICROANATOMY

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: -The name “white blood cell” derives from the physical appearance of a blood sample after centrifugation. White cells are found in the buffy coat, a thin, typically white layer of nucleated cells between the sedimented red blood cells and the blood plasma. The scientific term leukocyte directly reflects its description.
