Description:This trichrome-stained photomicrograph revealed numbers of white blood cells (WBCs), otherwise known as leukocytes. These blood cell are not oxygen-carriers like the red blood cells (RBCs), but act as members of the body’s defense mechanism, fighting the constant onslaught of pathogenic invaders such as bacteria, and foreign debris.
When compared to their cousins the erythrocytes, or RBCs, the leukocytes are larger in size, and much fewer in numbers, i.e., 8000/mm3. Leukocytes are categorized into two main groups, granular leukocytes, i.e., neutrophils, eosinophils and basophils, and the nongranular leukocytes, i.e., lymphocytes and monocytes.
