In humans, ____ is the difference between systolic and diastolic pressure.
A
40 mm Hg
B
20 mm Hg
C
0 mm Hg
D
None of the above
Explanation: 

Detailed explanation-1: -The top number (systolic) minus the bottom number (diastolic) is the pulse pressure. For example, if the resting blood pressure is 120/80 millimeters of mercury (mm Hg), the pulse pressure is 40-which is considered a healthy pulse pressure.

Detailed explanation-2: -A diastolic blood pressure of somewhere between 90 and 60 is good in older folks. Once you start getting below 60, that makes people feel uncomfortable. A lot of older folks with low diastolic pressures get tired or dizzy and have frequent falls.

Detailed explanation-3: -Blood pressure ranges Normal: less than 120 systolic and 80 diastolic. Elevated: 120–129 systolic and less than 80 diastolic. Stage 1 hypertension: 130–139 systolic or 80–89 diastolic. Stage 2 hypertension: at least 140 systolic or at least 90 diastolic.
