Mammal Heart Specimen

Many mammal hearts are similar to that of a human heart, which makes this dissection specimen great for studying both internal and external anatomy of the heart.

This plain preserved specimen can be used instead of a cow's heart for dissection labs. This mammal heart specimen will typically be from sheep; however, a pig or goat heart may be substituted due to limited availability of sheep hearts.

With a scalpel in hand, elementary, middle, and high school students can learn so much about a mammal 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 mammal 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.
