Why do my cheeks turn red when I am embarrassed?

Basically, your cheeks turn red when you are embarrassed is the blood vessels. It could be your whole face. Some people just blush and their whole face turns red. But the blood vessels near the surface of the skin will open up. It's just a response that we have to like an embarrassment because our bodies are set up for either fighting or getting away from a situation that is dangerous. Well an embarrassing situation is in that line and it causes our blood vessels to open up. Blood flows through them: makes the skin red and that's where our blush comes from.
