Question

The values obtained when taking blood pressure, such as 120/80,

a. exactly match the pressures inside the ventricle during systole and diastole.
b. represent the pressure in the major arteries during ventricular systole and diastole.
c. are the same in both the pulmonary and systemic circuits.
d. reflect the difference in blood pressure between the aorta and arterioles.
e. reflect the pressures associated with atrial and ventricular systole.

Answer 1

The correct answer will be option B.

Step-by-step explanation:

Blood pressure represents the pressure of the blood in the major arteries of the body.

This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.

The blood pressure decrease in the artery due to ventricular diastole during which ventricles relaxes. This lower number of blood pressure is known as diastolic blood pressure which is 80 mm of Hg.

Thus, option B is the correct answer.
