Heart disection

HEART DISECTION

First, we put all the materials on the table and take out the heart og bag. Lorena take a photo of the heart on the tray.

Second, we put the pencils in the vessels: a red pencil in the aorta arterie, an orange pencil in the pulmonary arterie, a yellow pencil in the cave vein and a light orange pencil in the pulmonary vein. then we differenciate the right part and the left part of the heart.

 Third, we cut the heart in two, to differenciate the ventricles. After located the ventricles , we put again the pencils into the vessels. And we find the valves.
