A person’s blood pressure is measured as 110/70 mm Hg.

The diastolic pressure is 110
110 is the pressure resulting from the contraction of the ventricle
The systolic pressure is determined when there is laminar flow of the blood
All of these are correct

Expert Answer

Step 1

Blood pressure is influenced by the contractile activities of the heart and conditions and activities of the blood vessels. The pumping of the heart generates blood flow. Blood Pressure is the force that blood exerts against blood vessel walls. Blood pressure is expressed in millimeters of mercury (mm Hg). For example, a blood pressure of 120 mm Hg is equivalent to a pressure exerted by a column of mercury 120 mm high.

Step 2

Diastolic 

When the heart is in a relaxation period or the minimum arterial pressure during relaxation. It is the lowest pressure in the artery. It's a result of ventricular diastole (relaxation) and is usually around 80 mm Hg.

 

Systolic

The blood pressure when the heart is contracting. It is the maximum arterial pressure during contraction. It is the result of ventricular systole or contraction. It is normally about 120 mm Hg.

The blood pressure of adult humans is 120/80 mmHg.

 

Step 3

Laminar Flow 

Blood flows faster in the center of a vessel than near the sides, because the blood near the sides are hitting the walls o...
