Document Summary
In parallel because you want specific organs to have their own specific flow respective to how much blood they need. Left ventricular wall is thicker than the right ventricular wall. This is because the left must develop a pressure that is at least 10x larger. Right ventricle= flap of muscle on the cylindrical left ventricle. 2 between atria and ventricles (atrial-ventricular valves; bicuspid and tricuspid valve see picture) 2 between the outlet of the ventricles to the arteries (aortic and pulmonic valves) see slides on valves. Papillary muscle rapture mitral regurgitation mitral valve replacement. If you get stabbed in the heart, for example, blood seeps out into the pericardium. Or you could have a pericardial infection producing fluid. The area of the ventricle becomes smaller, blood output and blood pressure drops to the point where you could die. see slides reviewing anatomy and functions. Atrial fibrillation: atria don"t pump- you don"t really need your atria.
