Suppose you measure a standing person’s blood pressure by
Chapter 11, Problem 33(choose chapter or problem)
Problem 33PE
Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.500 m below the heart. Calculate the pressure you would observe (in units of mm Hg) if the pressure at the heart were 120 over 80 mm Hg. Assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large).

ANSWER:
Solution to 33PE
Step 1 of 3
We have to calculate the blood pressure in a person’s legs at a position 0.5m below the heart. The blood pressure at the heart is 120/80 mmHg. As the blood flow down the body through the arteries, the blood pressure increases because of increase in height.
is the height
is the density of blood.
is acceleration due to gravity.
