Study Notes
White Blood Cells (WBCs)
- WBCs offer rapid and strong defense against infections.
- Lymphocytes are produced in lymphoid tissues like lymph glands, spleen, and thymus, as well as in bone marrow and Peyer’s patches in the gut.
- Bone marrow stores about three times more WBCs than those circulating in blood, providing a 6-day supply.
- Neutrophils initiate the inflammatory response by being the first cells to leave the bloodstream and enter inflamed tissues.
- Monocytes migrate to inflamed tissues and differentiate into macrophages.
Inflammatory Process
- Inflammation serves as a protective mechanism against pathogens, toxins, and injuries.
- Leukocyte extravasation (transmigration) involves the movement of WBCs from the bloodstream into tissues during inflammation.
- Chronic inflammation occurs when an inflammatory response persists despite the removal of threats.
Monocyte-Macrophage Cell System
- Comprised of monocytes, mobile and fixed macrophages, and specialized endothelial cells in tissues like bone marrow, spleen, and lymph nodes; known as the Reticuloendothelial System (RES).
- Functions include removing foreign objects and toxins, forming new blood cells, and clearing waste materials.
Characteristics of Inflammation
- Inflammation creates a "walling off" effect to isolate the injury, preventing the spread of bacteria and toxins through fibrinogen clots.
- Local vasodilation and increased capillary permeability are caused by histamine release from mast cells during inflammation.
Impact of Leukemia
- Characterized by high counts of abnormal WBCs and hampers the production of functional leukocytes.
- Leukemic cells produce rapidly, leading to increased demand for nutrients and energy depletion in the body.
- Types of leukemia include Acute Myelogenous Leukemia, Chronic Myelogenous Leukemia, Acute Lymphocytic Leukemia, and Chronic Lymphocytic Leukemia.
Types of Macrophages
- Various specific types of macrophages exist, such as microglia (in the CNS), intestinal macrophages, histiocytes, and alveolar macrophages (in the lungs).
