    In old age arteries carrying blood in the human body become narrow resulting in an increase in the blood pressure. This follows from:

    A) Pascal's law

    B) Stoke' slaw

    C) Bernoulli's principle

    D) Archimedes principle

    Correct Answer: C

    Solution :

    As blood flows from narrow arteries to wider one, velocity decrease as per rule of Bernoulli?s p\[\operatorname{P}+\frac{1}{2}\rho {{\operatorname{v}}^{2}}=Constant.\] It means, as velocity decreases, pressure increase.
