Human Body

by JE

In Science, we are learning about the human body. We know that food and water are really important. The left side of the heart exchanges carbon dioxide for oxygen. Cells in our body grow at least 1,000,000 times every 2 seconds! The slower your heart beats, the more athletic you are. You should be more athletic, so you can be healthy. Maybe you can give your organs to other people when you die.
