Document Summary
Inflammatory response: the inflammatory response is a sequential reaction to cell injury. It neutralized and diluted the inflammatory agent, removed necrotic materials, and established an environment suitable for healing and repair: an infection involves invasion of tissues or cells by microorganisms such as bacteria, fungi, and viruses. After release of histamine and other chemicals by the injured cells, the vessels dilate. In tissues, the clot functions to trap bacteria, prevent their spread, and serve as a framework for the healing process. Stored in granules of basophils, mast cells, platelets. Stimulates smooth of the gi tract muscle contraction. Produced from precursor factor kininogen as a result. Cause contraction of smooth muscle and of activation of a hageman factor (xii)of clotting vasodilation. Cytokines: neutrophils chemotaxis, neutrophils are the first leukocytes to arrive at the injury site (usually writhing 6 to 12 hours). They phagocytize (engulf) bacteria"s, other foreign material, and damaged cells.
