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. Bernoulli's principle
D. Archimedes’ principle

Answer

C

Explanation

According to equation of continuity, `av=a consta nt`. It means as area increases, velocity decreases. Thus, as blood flows from narrow arteries to wider increases.
According to Bernoulli's theoram , `P + 1/2 rhov^(2) = a consta nt`
it means, as velocity decreases, pressure increases. thus, when arteries becomes narrow, blood pressure increases.
