If you are lying down and stand up quickly, you can get dizzy or feel faint. This is because the blood vessels don't have time to expand to compensate for the blood pressure drop. If your brain is 0.4 m higher than your heart when you are standing, how much lower is your blood pressure at your brain than it is at your heart? The density of blood plasma is about 1025 kg/m3 and suppose your maximum (systolic) pressure of the blood at the heart is 118.8 mm of Hg (Note that 120 mm of Hg = 16 kP = 1.6 x 104 N/m2). Since most doctors still use mm of Hg, give your result in those units.
Pressure at brain =_______mm of Hg.

to know the signs of stroke and act quickly if you suspect someone
is having one. Stroke is the fourth leading cause of death in the
United States, and causes more serious long-term disabilities than
any other disease. Older people are at higher risk. You can take
