This is a 4-page document chock-full of pertinent information on the human circulatory system and human heart. Some of these notes have already been put into open notes format (this is indicated on the document). The rest of the notes ('board notes' that the students take down by hand into their notebooks) are a supplement to the open notes. It has lots of great color pictures that are anatomically labeled for class discussion. You can use this information any way you choose.
