Any liquid that has a pH less than 7 is called acidic, a pH above 7 is basic or alkaline.

KIM [24]

As blood pressure increases and the hearts is working harder the most vulnerable arteries area are those Located near the heart, because they are absorbing the most shock.

Explanation:

When the heart pumps blood, the highest pressure is felt close to the heart. This is why the aorta, the artery that carries blood away from the heart is made up of thick walls to withstand this pressure, otherwise, these vessels would rupture. Away from the heart, this pressure lessens, and the blood vessels are not so thick-walled.
