The pressure exerted against the walls of the artery when the left ventricle contracts is called the:

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

Answer: (C)

During ventricular contraction, the heart ejects blood and arterial pressure reaches its peak. This peak pressure is called systolic pressure. It reflects the force the heart generates to push blood into the arterial system. Diastolic pressure is the pressure when the heart is relaxed and filling. Mean arterial pressure is the average pressure in the arteries over the cardiac cycle, accounting for both phases. Pulse pressure is the difference between systolic and diastolic pressures. Since the question asks for the pressure against arterial walls specifically during contraction, the correct term is systolic pressure.
