Question

Which of the following statements are correct with respect to blood pressure?

• A. Blood pressure inside the artery during contraction is systolic pressure.
• B. Blood pressure inside the vein during relaxation is diastolic pressure.
• C. Normal diastolic pressure is 120 mm of Hg.
• D. Normal systolic pressure is 120 mm of Hg.

Answer 1

Answer: (A), (D)

Normal systolic pressure is 120 mm of Hg.

• Blood continuously flows through the blood vessels because of contraction and relaxation of the heart.
• Due to contraction of the heart, pressure is exerted on the walls of the arteries known as blood pressure.
• The pressure of the blood inside the artery during contraction is called systolic pressure, while during relaxation is called diastolic pressure.
• Normal systolic pressure is 120 mm of Hg and diastolic pressure is 80 mm of Hg and is measured by sphygmomanometer.
