Which pressure occurs in arteries during heart contraction?

• A. Systolic Blood Pressure
• B. Diastolic Blood Pressure
• C. Mean Arterial Pressure
• D. Pulse Pressure

Answer: (A)

During ventricular contraction, arterial pressure rises to its peak as blood is ejected into the arteries; this peak is the systolic blood pressure. Diastolic pressure is the pressure when the heart is relaxed and filling, not contracting. Mean arterial pressure is the average pressure over the cardiac cycle, and pulse pressure is the difference between systolic and diastolic pressures. So the pressure during contraction is the systolic blood pressure.
