Video Summary:
At the beginning of the ventricular systole, the aortic pressure is at its lowest point. With the opening of the aortic valve and ejection of blood, the pressure in the aorta increases. It even exceeds the pressure in the ventricle. But the inertia of the blood keeps the aortic valve open for a while. Then with decreased ejection, the pressure starts falling. Towards the end of the ejection phase, the backflow of the blood produces a dicrotic notch. during diastole, the blood keeps moving forward so there is a gradual fall in the pressure. The next cycle begins with the next systole.
