In old age arteries carrying blood in the human body become narrow resulting in an increase in the blood pressure. This follows from
Text Solution
Verified by ExpertsThe correct answer is:
C
According to equation of continuity av = a constant
It means as area increases, velocity decreases.
Thus as blood flows from narrow arteries to wider one, velocity decreases
According to Bernoulli’s theorem, 
constant
It means as velocity decease pressure increases
Thus, when arteries become narrow, blood pressure increases.
