Question

The blood pressure at the feet is more than blood pressure in head. Explain why?

Answer 1

The pressure of liquid column is given by $p=hpg$, where $h$ is depth, $p$ is density and $g$ is acceleration due to gravity.
Therefore, pressure of the liquid column increases with depth. The height of the blood column in a human body is more at feet than at the brain. Therefore, the blood pressure in humans is greater at the feet than the brain.
