Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
what is the measurement of blood pressure while the heart ventricles are contracting called?
A
diastolic pressure
B
systolic pressure
C
aorta pressure
D
artery pressure
Explanation: 

Detailed explanation-1: -Systolic pressure is the maximum blood pressure during contraction of the ventricles; diastolic pressure is the minimum pressure recorded just prior to the next contraction. The blood pressure is usually written as the systolic pressure over the diastolic pressure (e.g., 120/80 mm Hg).

Detailed explanation-2: -The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.

Detailed explanation-3: -Systolic blood pressure, the top number, measures the force the heart exerts on the walls of the arteries each time it beats. Diastolic blood pressure, the bottom number, measures the force the heart exerts on the walls of the arteries in between beats.

Detailed explanation-4: -Blood pressure represents the force (pressure) exerted by blood against the arterial walls during a cardiac cycle. <kt>Systolic pressure<kt>, the higher of the two blood pressure measurements, occurs during ventricular contraction (systole) as the heart propels 70 to 100 mL of blood into the aorta.
