Which of the following factors contributes the least to the higher systolic pressure compared to diastolic pressure?


 

Option: 1

The volume of blood in the heart during systole


Option: 2

Contraction of arteries during systole


Option: 3

The resistance offered by blood vessels during systole

 


Option: 4

The forceful entry of blood into arteries during systole


Answers (1)

While the forceful entry of blood into arteries does occur during systole, it has a relatively lesser impact on the overall pressure difference between systole and diastole. The forceful entry of blood is primarily a consequence of ventricular contraction, which is driven by the factors mentioned in options 1, 2, and 3. Therefore, option 4 contributes the least to the higher systolic pressure compared to diastolic pressure.
