Why does ejection occur only when Left Ventricular Pressure (LVP) is greater than Aortic Pressure (AP)?
Why does ejection occur only when Left Ventricular Pressure (LVP) is greater than Aortic Pressure (AP)?
- To prevent blood backflow into the ventricle (correct)
- To protect the heart from excessive pressure
- To maintain a continuous blood flow through the aorta
- To optimize oxygen delivery to tissues
How does the heart compensate for high aortic pressure?
How does the heart compensate for high aortic pressure?
- By reducing coronary blood flow
- By decreasing Left Ventricular contractility
- By dilating the coronary arteries
- By increasing Left Ventricular contractility (correct)
