Side A ------ Side B What is the 3 main phases of healing? ------ 1. Inflammation phase 2. Proliferation phase 3. Maturation phase What is inflammmation phase? last? ------ It's the first phase of healing. prepares the wound for healing Lasts 1-6 days from injury What is proliferation phase? last? ------ second phase of healing. rebuilds the damaged structures and strengthenes the wound Lasts 3-20 days from injury What is the maturation phase? how long does it last? timeline applies? ------ 3rd phase of healing modifies the scar tissues into its mature form, 9 on (1-2 years) This timeline does not apply to every injury because more factors could affect the healing process ex) size, nutrition, medications, other infections etc. Major events in inflammation phse? ------ 1.vasoconstriction 2. vasodilation 3. clot formation 4. phagocytosis Major events in proliferation phase? ------ 1.epitheliaziation 2. fibroplasias/ collagen production 3. wound contracture 4. neovascularization Major events in maturation phase? ------ 1. Synthesis/ lysis balance, 2. Collagen fiber orientation, 3. Healed injury What is the Primary purpose of inflammation? ------ It's an immediate protective response attempt to destroy dilute or isolate the cells or agents that may be at fault. cardinal signs of inflammation (English and Latin) and give the cause of each. ------ heat Calor Increase vascularity swelling Tumor blockage of lymphatic drainage pain Dolar physical pressure of chemical irritation of pain sensitive redness Rubor increase vascularity english : loss of function ------ Latin : factio laesa pian and swelling explain the affects of vasoactive mediators ------ increase vascular permeablity, edema chemotactic factors ------ recruitment/ stimulation of inflammatory cells, acute inflammation PMSs, platelets; chronic inflammation - macrophages, lymphocytes, plasmas cells platelets and the coagulation system? ------ thrombus formation, vasoactive mediators (vascular permeability) what is Role of neutrophils? ------ predominate and release a number of factors that amplify the platelet aggregation response, initiate a coagulation cascade or act as chemoattractants for cells involved in the inflammatory phase. macrophages ------ replace neutrophils after 2 days from injury leukocytes? ------ are WBC that histamine attracts to the damaged tissue area Monocytes? ------ monocytes turn into macrphages Identify the most important cell in the inflammatory phase? ------ Neutrofils Summerize the major events in the inflmmatory phase? ------ vascular: vasodilation followed by vasocontriction at the capillaries, post capillary venules, and lymphatics. vasodilation mediated by chemical mediators - histamine, hageman factor, bradykinin, prostaglandins, complement fractions. slowing of blood flow. Margination, pavementing and ultimately emigration of leukocytes. Accumulation of fluid in the interstitial tissues resulting in edema. hemostatic ------ retraction and sealing off of blood vessels, platelets form clots and assist in building of fibrin lattice, which serves as the wound's Cellular ------ delivery of leukocytes to the area of injur to rid the area of bacteria and debris by phagocytosis. monocytes, the precursors of macrophages, are considered the most important cell in the inflammatory phase. macrophages produce a number of products essential to the healing process. immune ------ mediated by both cellular and humoral factors. activiation of the complrement system viathe alternative and classical pathways resulting in components that increase vascualr permeability, stimulate phagocytosis, and act as chemotactic stimuli for leukocytes
