In old age arteries carrying blood in the human body become narrow resulting in an increase in the blood pressure, this follows from

Options

A. Pascal's law
B. Stokes'law
C. Archimedes 'principle
D. Bernoulli's principle

Answer

D

Explanation

From Bernoull's principle in the horizontal stream line motion of a liquid the sum of pressure (P) and kineteic energy per unit volume of the liquid at any point is constant , hence `rho + 1/2 rhov^(2)`= constant
It si clear from this equation that a flowing liquid where the velocity of flow is less, the pressure is large and vice-verse. Hence, arteries carrying blood becomes narrow resulting in increase in the blood pressure.
