Question

An adult human with average health has systolic and diastolic pressures as

• A. 120 mm Hg and 80 mm Hg
• B. 50 mm Hg and 80 mm Hg
• C. 80 mm Hg and 80 mm Hg
• D. 70 m Hg and 120 mm Hg

Answer 1

Answer: (A)

120 mm Hg and 80 mm Hg

Blood pressure is the pressure against the walls of the blood vessels produced by the discharge of blood into them by contraction of the left ventricle.

Systolic pressure: The temporary rise in BP during the contraction of the heart is called systolic pressure.

Diastolic pressure: The temporary fall in BP during the relaxation of the heart is termed as diastolic pressure.

For a healthy resting adult person, the average systolic/ diastolic pressures are 120/80 mm Hg in arteries near the heart.

So, the correct answer is '120 mm Hg and 80 mm Hg'.
