How do arteries look?
Your arteries have three layers, each one with a unique job: The innermost layer, the one in contact with the blood as it flows through, is called the intima. It’s nice and slippery, like Teflon, so the blood can easily flow over it. The middle layer, called the media, supports the structure of the artery.
