Answer:
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.
The pressure of a liquid is given by the relation:
P = h?g
Where,
P = Pressure
h = Height of the liquid column
? = Density of the liquid
g = Acceleration due to the gravity
It can be inferred that pressure is directly proportional to height. Hence, the blood pressure in human vessels depends on the height of the blood column in the body. The height of the blood column is more at the feet than it is at the brain. Hence, the blood pressure at the feet is more than it is at the brain.
