Abstract
Your heart works as a team with your body’s blood vessels. Your heart pumps the blood, while blood vessels help the blood travel all over your body, just as a garden hose helps move water all around your garden. Blood carries oxygen and other nutrients to your muscles and organs and removes carbon dioxide and other wastes. These are very important chores for the blood! Sometimes doctors need to check whether the heart and blood vessels are working properly, or scientists may want to study how blood vessels work as people get older. To do this, a technique called ultrasound is used to take pictures and videos of the blood vessels and the blood moving through them. But how does sound create pictures? This article will explain how ultrasound works and how it can be used to examine blood vessels and the speed of the blood flow.
