The size of a sheep heart is similar to that of a human heart, making it a great preserved specimen for dissection and studying heart anatomy.

This is a plain preserved specimen of an adult sheep heart. It can be used instead of a cow's heart for dissection labs. Order 10+ to save extra for your class!

Through dissection, one can learn much about a sheep heart's internal anatomy. Discover what the right atrium, left atrium, right ventricle, left ventricle, aortic semilunar valve, bicuspid valve, tricuspid valve, interventricular spectrum, aorta, pulmonary vein and pulmonary artery, papillary muscles, inferior vena cava, blood vessels, and other parts of the heart look like.

Heart dissection reveals the intricacies required of a heart to pump blood. This hands-on experience shows students the differences between and roles of the right side of the heart and the left side of the heart in a memorable way.

Note: Preserved sheep heart specimens are initially treated with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced, first with water and then with a glycol solution, to produce a moist, low-fume specimen which will not decay over time.
