What is the normal pressure in the Aorta?

• A. 70-100 mmHg
• B. 90-140 mmHg
• C. 110-150 mmHg
• D. 140-180 mmHg

Answer: (B)

Pressure in the aorta is pulsatile, peaking during systole as the heart ejects blood. In a healthy adult, the systolic arterial pressure in the aorta typically ranges from about 90 to 140 mmHg, with an average around 120 mmHg. This makes 90–140 mmHg the best match for normal aortic pressure. The other ranges are either too low for the systolic peak or extend into values that would be considered high. Remember, diastolic pressure is lower and occurs when the heart is relaxed, but the question targets the systolic range.
