One of the animations we viewed in class today was the gas exchange animation

This animation is most likely older than I am (well at least older than you are) but still works for learning the pathway of blood through the body.


Just a cool graphic showing inside the heart chambers and the chordae tendinae or "heartstrings"


A simple review of the major blood vessels coming in and out of the heart and the heart chambers. Label the diagram on the back of your reading guide while watching this.
