APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -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-2: -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.
