Which statement correctly describes systolic blood pressure?

• A. It is generated when the heart contracts and forces blood into the arteries.
• B. It measures venous pressure during rest.
• C. It remains constant regardless of heart activity.
• D. It measures the pressure in the veins during systole.

Answer: (A)

Systolic blood pressure is the peak pressure in the arteries that occurs when the heart contracts and forces blood into the arterial system. During ventricular contraction (systole), the ventricles push blood out into the aorta and other arteries, causing arterial pressure to rise to its highest point. This peak reflects the arterial response to the heart’s ejection of blood and is what we record as the systolic reading. It’s distinct from diastolic pressure, which is the lower pressure in the arteries when the heart is relaxed between beats, and it’s not a measure of venous pressure. So the statement describing systolic pressure as generated when the heart contracts and pushes blood into the arteries is the accurate description.
