What are arteries?

Arteries are like pipes that carry blood from your heart to the rest of your body.

Imagine you're drinking water from a big cup. Your straw is like an artery, it helps the liquid (which is like blood) travel from the cup (like your heart) all the way to your mouth (like your muscles or brain). Just as your straw gets narrower or wider depending on how much you sip, arteries can change size to help more or less blood flow through.

Arteries are strong and stretchy, like a rubber band. When your heart beats, it pushes blood into the arteries, making them bulge slightly. Then, as the blood moves along, the arteries slowly relax, helping keep the blood flowing smoothly to your fingers, toes, and every part of you.

Sometimes, if something blocks an artery, like a clog in a pipe, it can make it harder for blood to reach where it needs to go. That’s why taking care of your heart and keeping your arteries healthy is so important!
