Here are the videos Lia showed in class about the different systems in the body:

Digestive System                        Circulatory System                      Blood Cells 

And, answering Mariano's question in class:

Why are red blood cells  red? 

Red blood cells contain hemoglobin, a molecule with iron that catches the oxygen.
Think of rust.

Rust happens because fo the oxygen in the air.The same happens to the iron in red blood cells. In contact with oxygen , it gets red.
