Systemic blood pressure of a person equals 120/65 mm Hg. Blood ejection into aorta occurs when left ventricular pressure exceeds:
- A. 100 mm Hg
- B. 10 mm Hg
- C. 90 mm Hg
- D. 65 mm Hg
- E. 120 mm Hg
Hint
Think about which pressure in the aorta the ventricle has to overcome at the moment the aortic valve is about to open, and where in the cycle that occurs.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
