NURS 3220 Lecture Notes - Lecture 14: Shortening, Statin, Pancreatitis
Document Summary
Contain thicker layer of smooth muscle: main artery is aorta. Contain valves to control reflux of blood flow back toward heart: main vein is the vena cava. Artery: muscle coat thicker in arteries, outer coat thicker in arteries. Contain valves to control reflux of blood flow. Type of arteriosclerosis: accumulation of plaque in the intima of arteries. Causes variable narrowing, or obstruction of intima lumen: develops silently over decades. Symptoms depend on: where the affected artery is. Periodontal disease: healthy teeth and healthy gums: ldl, crp (c reactive protein) blood test marker for inflammation high levels = inflammation, hdl, fibrinogen: blood clot formation. 3 fatty acids with a central glycerol: used in energy metabolism, most influenced by sugar in diet. Blood clotting components: myelin sheath of nerves. Cell membranes: most chronic diseases involve injury to cell membrane. Cell membrane repair: high density lipids ( healthy ) Raise: alcohol, niacin, fibrates, statins, smoking cessation, estrogen, weight loss, exercise.
