PHYSIOL 596 Chapter Notes - Chapter 7: Low-Density Lipoprotein, Angioplasty, Macrophage
Document Summary
The left ventricle has the thickest wall and strongest force of contraction. L ventricle> aortic semilunar valve > aorta. If any of these are blocked > heart attack pathways. Anastomoses : blood vessels with other connections that serve as alternate. This beating sound is the valves (tricuspid and bicuspids closing and opening) Heart diseases- problems in the blood vessels. Blood pressure is the friction when blood travels. These are lethal because they have the potential to get stuck in blood vessels. They come from vldl when they empty their lipid contents. Ldl is then transported back to the liver by the way of hdl. These collect excess cholesterol (ldl) and transport it back to the liver. Hdl uptakes the ldl>> foam cells>> plaque. Other side of plaque blood flow = less oxygenated blood. Cardiac conduction system= cells that send electrical signals to heart to beat. Fat and high blood pressure slowly deteriorates the blood vessels.
