Granular white blood cells are basophils, eosinophils, and neutrophils. White blood cells help us to fight viruses, bacteria, allergies, and even cancer. New York, McGraw Hill Professional. When released, their granules act as lysosomes to digest cellular macromolecules, destroying the neutrophil in the process. A white blood cell, also known as a leukocyte or white corpuscle, is a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and disease. Only a small number of platelets can be found in the bone marrow. Lymphocytes are cells that circulate in your blood that are part of the immune system. Neutrophils, eosinophils, and basophils are collectively known as granulocytes (gran -u-lo-sits), because their cytoplasms contain small, colored granules. ", Biologydictionary.net Editors. Other major blood components include plasma, white blood cells, and platelets. A U-shaped or kidney-shaped nucleus and abundant cytoplasm distinguish monocytes.
