26. Fever is a result of chemical mediators acting directly on the hypothalamus. The hypothalamus is responsible for controlling temperature in the body. An elevated body temperature stimulates phagocytosis and can also inhibit the growth of certain microorganisms. Leukocytosis is an elevation in the white blood cell, or leukocyte, with a count usually above 10,000/mm3. Typically, the individual has a white blood cell count of 5,000 to 10,000/mm3. Leukocytosis demonstrates the increased circulation of white blood cells to aid in healing. Plasma proteins are also increased as a result of the three plasma protein systems (complement, kinin, and clotting). These proteins are called acute-phase reactants and can be measured through the use of laboratory tests, such as C-reactive protein (CRP).
27. The erythrocyte sedimentation rate (also referred to as a sed rate, or ESR) is a nonspecific method of testing for inflammation. This means that, when elevated, inflammation is occurring somewhere in the body but the exact source or location is not identified by the test. During the inflammatory process, the coagulation cascade results in increased circulating levels of fibrinogen, which causes cells to stick together. When measured in a tube in the lab, RBCs exposed to the inflammatory process will fall faster and will clump together. The ESR test then measures (in mm/hr) the level of RBC stacking. The test takes about 45 minutes. Typically, a higher result equates to more severe inflammation.

28. Reduce blood flow to the site, decrease swelling, and block the action of chemical mediators.
29. Inflammatory phase—vascular and cellular response regulated by plasma protein systems and activated/inhibited by chemical mediators, the goal is to bring forth the products of healing to the site of injury and to remove foreign substances and necrotic tissue; proliferative phase—restoring structural integrity is dependent upon the delicate balance of tissue destruction and construction. Tissue lysis, or breakdown and removal, is accomplished through the work of enzymes that are needed to rid the body of the damaged tissue. Growth factors and matrix proteins are responsible for rebuilding the extracellular matrix (ECM), the layers of architectural structures that support the cells (basement membrane, connective tissue). Macrophage activity converts the provisional matrix into granulation tissue. Granulation tissue is a connective tissue characterized by extensive macrophages and fibroblasts, and the promotion of angiogenesis, or the generation of new blood vessels at the site. The generation of blood vessels, particularly capillaries, at the site is needed for oxygen/carbon dioxide exchange and to provide other nutrients to the newly developing tissue. Granulation tissue is most noted for the presence of an extensive network of capillaries. As the wound heals, granulation tissue loses the excessive capillary network and retains only that needed to support the final connective tissue matrix. The provisional matrix and specialized granulation tissue are no longer needed and are reabsorbed once the wound is healed and the final connective tissue matrix is in place. Parenchymal cells undergo resolution, regeneration, or replacement; remodeling phase—a process of continued tissue reconstruction that occurs over several months.
30. The basement membrane is a critical component of tissue healing and serves to provide a supportive architectural structure, support re-epithelialization, or the movement of epithelial cells to form a covering over the wound, store growth factors, restore neuromuscular function at the site, and support the development of parenchymal tissues, that is, those tissues made up of cells with a specific function, such as neurons, myocardial cells, and epithelial cells, at the site.
31. Labile cells constantly regenerate through mitosis, particularly epithelial cells of the skin, gastrointestinal tract, and urinary tract, and blood cells in the bone marrow. Stable cells stop regenerating when growth is complete but can resume regeneration if injured. Permanent cells, such as neurons, cardiac myocytes, and the lens of the eye, do not undergo mitosis and are unable to regenerate.
