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

This plain preserved specimen of an adult sheep heart can be used instead of a cow's heart for dissection labs.

With a scalpel in hand, elementary, middle, and high school students can learn so much about a sheep heart's internal anatomy. They'll discover the placements of parts such as the:

  • right atrium & left atrium,
  • right ventricle & left ventricle,
  • aortic semilunar valve, bicuspid valve & tricuspid valve,
  • interventricular spectrum,
  • aorta,
  • chordae tendineae,
  • pulmonary vein, pulmonary artery & pulmonary trunk,
  • papillary muscles,
  • inferior vena cava,
  • blood vessels,
  • and more!

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.
