प्रश्न
Explain why The blood pressure in humans is greater at the feet than at the brain
Advertisements
उत्तर १
The height of the blood column is more for the feet as compared to that for the brain. Consequently, the blood pressure in humans is greater at the feet than at the brain.
उत्तर २
The pressure of a liquid is given by the relation:
P = hρg
Where,
P = Pressure
h = Height of the liquid column
ρ = 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.
