A. Inflammations1. Regarding the mechanism of inflammation, explain how PRICE's steps can minimize Dave's inflammation. Inflammation is the cleaning of a wound, and we know it by redness, swelling, heat, and pain. The impact and deformation of his ankle killed cells, damaged fibers and changed the chemical composition of the interstitial fluid. Lysosomes release enzymes that destroy damaged cells and attack surrounding tissues. Debris, fluid, and dying cells build up, causing pressure, and histamine, heparin, and prostaglandins increase blood flow, vessel permeability, and pain. Ice helps relieve local temperature increase, and compression helps contract the vessels, reducing swelling. The elevation will also reduce swelling by decreasing blood flow to the area. Protecting the injury and resting will allow it to heal faster with fewer additional cells damaged (Martini 142-143).2. Although Dave was given a prescription painkiller, there are over-the-counter painkillers such as aspirin, acetaminophen, and NSAIDs (like Aleve). Choose one of these over-the-counter pain relievers and explain how it reduces pain. By blocking the effect of the enzyme, cyclooxygenase, the functions of prostaglandins, such as sensitization of pain receptors to mechanical and chemical stimuli and dilation of blood vessels, are diminished (Merck 408). Pain and swelling are reduced.B. Fainting1. Why did Suzie faint when she got up from the table? Explain the specific changes in her CVS that caused her to pass out. Sitting or standing up too quickly can cause fainting because the change in position causes blood to pool in the legs, leading to a drop in blood pressure. If Suzie fainted because she secretly didn't eat bre...... middle of paper ......c. 2011. .http://www.eatingproblems.org/epseffect.html “Physiology and psychology: performance criteria – Cardiac output”.
