My heart was broken……..





As G9 Coordinated Science (Biology) studied the circulatory system we had the opportunity to get up close and personal with a sheep’s heart. Before we started the dissection, we examined the external anatomy of the heart and identified the important blood vessels. We discussed the factors that increase the risk of damage or blockage of the coronary arteries that supply the heart with blood. The students enjoyed linking the theory of how the heart works with the opportunity to feel the heart (cardiac) muscle and put their fingers through each blood vessel to find out which chamber of the heart it connects to. We finished the lesson by watching part of a giraffe dissection to see how the wall of the left ventricle in this animal is even thicker to pump blood to the top of the giraffes head and back!
