Circulatory System

After meeting the lungs online at Khan Academy, we decided to Meet the Heart this week. While we love all the Khan Academy teaching videos so far, we find "How does the Heart Work?" by Mocomi Kids to be the most concise explanation of a rather convoluted system. Of course we can't learn without a catchy Circulatory Song!

Mapping out the circulatory system and playing The Circulation Game really helps us understand and appreciate the workings of our heart pump.

The objective of the game is to get the red blood cells to deliver oxygen and pick up carbon dioxide from different parts of the body, and to deliver sugar & protein from the intestines to the body while bringing waste to the kidneys.

Do you know: the "lub-dub" thumping sound of your heart comes from the heart valves snapping shut to prevent backflow.
