The Heart

The Heart

In science, 6^th Class were learning about the heart. We learned how the organ functions and how we can keep our hearts healthy. We also learned about the different parts of the heart. Ms. O’Callaghan decided we would learn much more by seeing the parts in real life so we got to dissect a sheep’s heart.

On Thursday the 4^th of February Ms. O’Callaghan brought in six sheep’s hearts, one for every group. We put on plastic gloves beforehand to ensure the bacteria wouldn’t spread. We each got to hold the heart and examine it. We found it interesting to see how fat can stick to the heart. Ms. O’Callaghan cut the heart in half for us. We could see the four chambers; the left atrium, the right atrium, the left ventricle and the right ventricle. We could also see the vena cava and the aorta. We also found some blood clots hiding in the heart!

It was really interesting to see the heart in real life. Everyone really enjoyed the lesson.
