What term is the measure of the force exerted by pumped blood on the walls of arteries?
Blood pressure is the force of the blood pushing against the artery walls. The force is made with each heartbeat as blood is pumped from the heart into the blood vessels. This is called systolic blood pressure. Blood pressure is also affected by the size of the artery walls and their elasticity.
What is used to measure the pressure exerted on the walls of the blood vessels during refilling of the heart?
Pressure is typically measured with a blood pressure cuff ( sphygmomanometer ) wrapped around a person’s upper arm, which measures the pressure in the brachial artery.
What is the main force driving the flow of blood away from the heart?
Mean arterial pressure is the force that drives the flow of blood through the circulatory system.
Which one of the following is the pressure exerted by the blood flowing through the arteries when the heart muscle relaxes?
When the heart pushes blood around the body during systole, the pressure placed on the vessels increases. This is called systolic pressure. When the heart relaxes between beats and refills with blood, the blood pressure drops. This is called diastolic pressure.
Which of the following is used to measure the pressure exerted?
A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure….Vocabulary.

| barometer | noun | an instrument that measures atmospheric pressure. |
Which of the following is used to measure the pressure exerted on the walls?
Systolic pressure gauges the maximum pressure exerted by the blood flow on the artery walls. Diastolic pressure gauges the minimum pressure exerted by blood flow. For example, normal combined blood pressure for an adult is 120/80.
Which number refers to the systolic pressure?
For example, 120/80 mm Hg. The top number refers to the amount of pressure in your arteries during the contraction of your heart muscle. This is called systolic pressure. The bottom number refers to your blood pressure when your heart muscle is between beats.
