What is this?
Your body has an amazing transportation system made of tubes called blood vessels that carry blood everywhere. Arteries, veins, and capillaries are the three main types of these vessels, working together to deliver important stuff and collect waste. They make sure every single part of your body gets what it needs to stay healthy and strong.

Capillary
These are super tiny vessels, like microscopic tunnels, where oxygen and food swap places with waste products.
Blood Flow Arrows
These arrows show the path blood takes as it moves through the different vessels in your body.
