Question
In old age arteries carrying blood in the human body become narrow resulting in an increase in the blood pressure. This follows from
Solution
This follows from the principle of fluid dynamics. As per this principle, when the area of a pipe (in this case, the artery) decreases, the speed of the fluid (in this case, the blood) flowing through it increases. This is known as the Bernoulli's principle.
Here are the steps:
-
As a person ages, the arteries can become narrow due to various factors such as the buildup of plaque, a condition known as atherosclerosis.
-
This narrowing of the arteries reduces the area through which the blood can flow.
-
According to Bernoulli's principle, when the area through which a fluid flows decreases, the speed of the fluid increases.
-
In the context of blood flow, this increased speed translates to increased pressure.
-
Therefore, the narrowing of arteries in old age can result in an increase in blood pressure.
