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

The blood pressure is higher at feet than at brain, as the blood has to be pushed back to the heart from feet against the force of gravity and it has to travel a large distance from feet to heart. While in case of brain, the distance is less and not much force is required.

The height (h) of the blood column at the feet is large as compared to at the brain . Hence, blood pressure is more at feet that at the brain according to this formula, p=hdg where d = density of the medium(blood).
