Question

complete each sentence by selected the proper term from each drop - down.

1. the highest pressure exerted on the arterial walls during the heart cycle is referred to as (click to select)
2. when one third of pulse pressure is added to the diastolic pressure, a good estimate of (click to select) is obtained.
3. the (click to select) is measured when the heart is relaxing and represents the lowest pressure exerted in the walls of the arteries during the heart cycle.
4. subtracting the sbp from the dbp results in (click to select), which is directly proportional to the overall strength of ones pulse.

Explanation:

1. The highest pressure in the arterial walls during the heart cycle is systolic blood pressure (SBP), which occurs when the heart contracts.
2. Mean arterial pressure (MAP) is estimated by adding one - third of pulse pressure to diastolic pressure. This is a standard formula in cardiovascular physiology: \(MAP = DBP+\frac{1}{3}(SBP - DBP)\).
3. Diastolic blood pressure (DBP) is the pressure when the heart is relaxing, representing the lowest pressure in the arterial walls during the heart cycle.
4. Pulse pressure is calculated by subtracting diastolic blood pressure (DBP) from systolic blood pressure (SBP) (\(Pulse\ Pressure=SBP - DBP\)), and it is related to the strength of the pulse.

Answer:

1. systolic blood pressure (SBP)
2. mean arterial pressure (MAP)
3. diastolic blood pressure (DBP)
4. pulse pressure
