Question

In arteriosclerosis, hardened arteries cannot expand to handle the blood that enters the vessel when the heart contracts. Therefore, pressure ________ in the artery and causes the heart to work _________.
A) increases, more
B) decreases, less
C) decreases, more
D) increases, less

Answer 1

Answer: A. pressure increases in the artery and causes the heart to work more

Explanation: the answer is correct because I did the USA test prep

Answer 2

A. pressure increases in the artery and causes the heart to work more

When the artery cannot expand the pressure builds up in the smaller space that remains.  As the pressure builds, the heart has to work harder to push the same amount of blood through that smaller opening.

Hope that helps.
