Question 36 of 60

36) Assuming the circulatory system in humans obeys Bernoulli’s principle of fluid dynamics, which of the statements most accurately compares the blood pressure in a capillary of the neck to a capillary with an equal cross-sectional area in the right knee?

The pressure in the neck is greater than the pressure in the knee because of the increase in pressure head
The pressure in the neck is equal to the pressure in the knee because of the equal dynamic pressure according to the continuity equation
The pressure in the knee is greater than the pressure in the neck because of the increase in pressure head
An accurate comparison cannot be given without knowledge of the fluid’s density and viscosity
