Question

Consider the following statements regarding blood pressure.
1. It is the pressure exerted by the blood on the walls of any blood vessel.
2. It decreases in the arteries as the distance from the heart increases.
3. It is lower in the capillaries than in the arteries.
4. It is usually lower in women than in men.

• A. 1 and 4 are correct.
• B. 2, 3 and 4 are correct.
• C. 1 and 3 are correct.
• D. 1, 2, 3 and 4 are correct.

Answer 1

The correct option is D 1, 2, 3 and 4 are correct.

Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels. It is usually measured at a person's upper arm. Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of mercury (mm Hg). It is one of the vital signs along with respiratory rate, heart rate, oxygen saturation, and body temperature. Normal resting blood pressure in an adult is approximately 120/80 mm Hg.

It decreases in the arteries as the distance from the heart increases.

It is lower in the capillaries than in the arteries.

It is usually lower in women than in men.
