QUESTION:
Problem 73GP
The contraction of the left ventricle (chamber) of the heart pumps blood to the body. Assuming that the inner surface of the left ventricle has an area of 82 cm2 and the maximum pressure in the blood is 120 mm-Hg, estimate the force exerted by that ventricle at maximum pressure.
ANSWER:
Solution 73GP:
We have to determine the force exerted on the left ventricle (chamber) of the heart pumps blood to the body during contraction.
Step 1 of 2
Concept:
Pressure acting on the body is defined as the ratio of the force applied per unit cross sectional area. Mathematically,
