- 1. Hemodynamics Physics of Blood flow in the circulation
- 4. Circulation Schematic Lungs Tissues Left Side of Heart Right Side of Heart A V V A Pulmonary Vein Pulmonary Artery Aorta Sup. & Inf. Vena Cava Mitral Valve Pulmonary Valve Aortic Valve Tricuspid Valve
- 6. Opening, Closing of Valves - Depends on Pressure differences between blood in adjacent areas
- 23. Principles of Sphygmomanometry Cuff inflated until brachial artery compressed and blood flow stopped what kind of sound?
- 24. turbulent flow Slowly release pressure in cuff:
- 29. 1. The LV pressure begins to rise after the QRS wave of the ECG 2. Pressure rises until the LV pressure exceeds the aortic pressure The blood begins to move from the ventricle to the aorta 3. As blood enters the aorta, the aortic pressure begins to rise to form the systolic pulse 4. As the LV pressure falls in late systole the aortic pressure falls until the LV pressure is below the aortic diastolic press. 5. Then the aortic valve closes and LV pressure falls to LA pressure
