The Circulatory System

We've been studying the Circulatory System. Here's a few things we don't want to forget:

Beca
When you are cold, the blood doesn't go everywhere in your body. It stays mostly in your organs. When you're hot, the blood goes everywhere in your body.

Nathan
Your heart never stops beating from when you are born to when you die. Your heart is beating when you are asleep. Sometimes I wonder if your heart ever takes a break . . . No, it doesn't.

Verena
I want to remember that the systemic circuit takes blood to the body. The pulmonary circuit takes blood to the lungs.
