Why blood pressure is greater at the feet than at the brain
The pressure in a fluid column is given by P = ρgh, where ρ is density, g is gravity, and h is height of the column.
In the human circulatory system, the height of the blood column is least at the brain and greatest at the feet. Therefore, the hydrostatic pressure contribution is highest at the feet, making the blood pressure greater there than at the brain.
