Study Notes
Types of White Blood Cells and Their Functions
- Blood is composed of formed elements and plasma. The formed elements are red blood cells, platelets, and white blood cells (WBCs).
- Hematopoietic stem cells (HSCs) in the bone marrow differentiate into different types of blood cells through a process called hematopoiesis.
- The three major categories of formed elements are red blood cells, platelets, and white blood cells.
- White blood cells can be subdivided into granulocytes (with granules in their cytoplasm) and agranulocytes (without visible granules).
- Neutrophils, also called polymorphonuclear neutrophils (PMNs), are frequently involved in eliminating and destroying extracellular bacteria through phagocytosis and degranulation.
- Eosinophils are granulocytes that protect against protozoa and helminths and play a role in allergic reactions.
- Basophils have cytoplasmic granules of varied size and are important in allergic reactions and other responses that involve inflammation.
- Mast cells are very similar to basophils and play a similar role in allergic and inflammatory reactions but are found in tissues rather than circulating in the blood.
- Agranulocytes can be categorized as lymphocytes or monocytes. Natural killer cells (NK cells) are a type of lymphocyte that use nonspecific mechanisms to recognize and destroy abnormal cells, such as cancer cells or virus-infected cells.
- NK cells recognize abnormal cells through a complex process of identifying inhibitory and activating molecular markers on the surface of the target cell.
- Monocytes differentiate into tissue-specific phagocytes called macrophages and dendritic cells, which are important promoters of the immune response through their production and release of cytokines.
- Macrophages and dendritic cells provide an essential bridge between innate and adaptive immune responses.
