Systolic pressure is higher than diastolic pressure due to :-a)Volume ...
Explanation:
Systolic pressure is the maximum blood pressure exerted by the heart during contraction (systole), whereas diastolic pressure is the minimum blood pressure exerted by the heart during relaxation (diastole). The difference between systolic and diastolic pressure is known as pulse pressure.
The correct answer is option 'D'.
Blood is forced into arteries during systole:
During systole, the heart contracts, and blood is pushed out of the heart into the aorta and then into the arteries. This causes the pressure in the arteries to increase, resulting in systolic pressure. The volume of blood in the heart is not greater during systole, as the amount of blood in the heart remains the same throughout the cardiac cycle. Arteries do not contract during systole, but they do contract during diastole, which helps to maintain diastolic pressure. Blood vessels offer resistance to flowing blood during systole and diastole, but this does not explain why systolic pressure is higher than diastolic pressure.
Therefore, the correct answer is blood is forced into arteries during systole.
Systolic pressure is higher than diastolic pressure due to :-a)Volume ...
Systolic blood pressure is the blood pressure during ventricular contraction,diastolic is during ventricular relaxationwhile ventricular contraction,blood is forcefully pumped into the respective arteries,hence systolic blood pressure is more.
