The Heart of the Matter

The boys in Mr. Duignan's 6th class were studying the circulatory system last week. What better way to gain an appreciation for the mechanics of this complex, fascinating system than to dissect a mammalian heart? We chose to work with sheep hearts, sourced from a local butcher, since they are similar in size and shape to the human heart.

The boys were extremely professional in adhering to strict health and safety guidelines when handling the hearts. They were able to observe, at close quarters, the chambers of the heart, valves, major blood vessels and even the chordae tendineae, better known as the heart strings.

The activity was enlightening and fun and gave a great insight into the amazing pumping power of the mammalian heart.
