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. Stoke's law
C. Bernoulli's principle
D. Archimede's principle

Answer

C

Explanation

Bernoulli's principle. If one has water flowing in a horizontal tube, the pressure will be the same. But the velocity will be more. If there is any obstruction, then pressure will also build up. Bernoulli's law is valid for luminous flow. In old age arteries get thicker and narrow.
