Question 1:

During which phase of the cardiac cycle do the ventricles contract and pump blood into the arteries?

Explanation: During systole, the ventricles contract and pump blood into the arteries. Diastole is the relaxation phase of the cardiac cycle.

Question 2:

Which of the following represents the highest pressure in the arteries during the cardiac cycle?

Explanation: Systolic pressure represents the highest pressure in the arteries during the cardiac cycle. It occurs when the ventricles contract and eject blood into the arteries.

Question 3:

What is the average resting value for diastolic pressure?

Explanation: The average resting value for diastolic pressure is around 80 mmHg. Diastolic pressure represents the lowest pressure in the arteries during the relaxation phase of the cardiac cycle.

Question 4:

What is the term used to describe the difference between systolic and diastolic pressure?

Explanation: Pulse pressure is the term used to describe the difference between systolic and diastolic pressure. It provides information about the strength and elasticity of the arterial walls.

Question 5:

What is the average value for mean arterial pressure?

Explanation: The average value for mean arterial pressure is calculated as diastolic pressure plus one-third of the pulse pressure. It is typically around 80 mmHg.
