This week, Year 6, as part of their study of ‘Animals, including humans’, continued their investigation of the human circulatory system and cardiac function. The children delved further than ever before by observing the dissection of an ox’s heart. Firstly, the intrepid scientists carried out a risk assessment to ensure that everyone stayed safe during the lesson.  The children then noted the thick, dark red   muscle and crumbly white fat on the outside of the heart. Then, with great care, the heart was sliced open to reveal the principal chambers (ventricles and atria) and major blood vessels (vena cava and aorta). They followed the blood’s path with string to demonstrate circulation. Hopefully it was an experience they will never forget!
