Aortic insufficiency (aka aortic regurgitation) is a condition caused by a leaky aortic valve, i.e., the valve between the left ventricle and the aorta. During ventricular diastole, this causes some blood to flow in the reverse direction, from the aorta into the left ventricle. Which one of the blood pressure readings below would you most expect to find in a case of aortic insufficiency? The values are systolic pressure / diastolic pressure, both in mm Hg.

A.50 / undetectable

B.95 / 80

C.120 / 80

D.130 / 40

Which one of the following statements is true?

1. A.All veins in the body contain partly deoxygenated blood.
2. B.Atrial systole and ventricular systole occur simultaneously.
3. C.All types of blood vessels contain at least some smooth muscle in their walls.
4. D.During ventricular diastole, blood pressure in the aorta is lower than blood pressure in the left ventricle.
5. E.None of the above statements is true.
