The Anatomy of Blood Pressure

Understanding the anatomy of the heart and the large and small arteries of the cardiovascular system can help you understand why managing your blood pressure is important.

In the heart, the ventricles create systolic pressure when they contract to force blood out of the heart. And they create diastolic pressure when they relax to refill with blood. The arteries serve to move blood through the system to the organs.

This module shows you how the artery structures work to move blood and how they can affect your blood pressure.
