Explain why

The blood pressure in humans is greater at the feet than at the brain

Human body is filled with blood which constitutes for the hydrostatic pressure. Hydrostatic pressure depends on the height of the liquid column.

P = ρgh

Where, P = Pressure

h = height of the liquid column

g = Acceleration due to gravity = 9.8 m/s

Height of the blood column at feet is greater than the height of blood column at the brain.

Therefore blood pressure in humans is greater at the feet than at the brain.
