➢ Arteries carry blood away from your heart. Arteries have thick walls so they can handle the high pressure and velocity that expels your blood out of your heart.

Explanation:

As per the new ACC/AHA guidelines, blood pressure >130/80 is high blood pressure or hypertension. Emphasis is given to multiple readings obtained on multiple occasions rather than a single reading. This is because various factors can influence a single blood pressure reading including prior activity, smoking, caffeine intake, cuff size, stress etc.

Refer to the section on blood pressure to understand how blood pressure works and how it is measured. Briefly, blood pressure is represented as two numbers. The higher number represents the spike in blood pressure when the heart pumps blood into the arteries with each heart-beat. Like a wave travelling forward and this is felt as a pulse. The lower number represents the pressure within the arteries in between the heart-beat. Read about the effect of salt on blood pressure.

Why do we have blood pressure?

Blood pressure is required to push the blood to various organs. Like a garden hose, without continuous water pressure applied by the tap, water will not flow and come out of the other end. Too low water pressure and the water flow dries out. Too high pressure and the water jets out too fast and may even rupture the pipe at the weak segments.

What effects does high blood pressure or hypertension have?

On the artery:

Too much pressure in the arteries is a constant stress on the artery wall. High pressure causes changes in the artery, making them firm. This is like a garden hose replaced with a lead pipe, inflexible and non-expandable. This increases the resistance to blood flow and further increases the pressure
