Document Summary
Major benefits of compliance: maintains lower systolic blood pressure, converts intermittent flow into continuous flow. Elasticity allows for continuous flow throughout the heart. Densible tube allows to keep systolic blood pressure lower. Aorta elasticity allows to have continuous flow through circulation which helps to maximize 02 carrying capacity to all of the erythrocytes. Distensible tube: keeps systolic blood pressure low because as the aorta expands during systole it creates a larger space for blood to occupy keeping pressure lower. Pulse pressure is not a fixed measure it can change minute by minute. Aorta pressure: the dicrotic notch is a land mark that distinguishes the break between the systolic and diastolic pressure. It is also an indicator of when he valves close. Mean arterial pressure (93mmhg) is weighted more towards diastolic because most of the cardiac cycle is spent in diastolic. It can access by integrating the area under the curve or by doing the map calculation.
