The intervalvular, or membranous, septum, a fibrous continuity between the mitral valve and the aortic valve is present in humans but absent in sheep.
Why are sheep hearts used to study the human heart?

What is the difference between a human heart and a pigs heart?
The human heart was trapezoidal in shape. The pig heart, in contrast, was a broad cone shaped organ. In humans, the left atrium received the four pulmonary veins whereas in pig it received two pulmonary veins.
What is the purpose of dissecting a sheep heart?
A sheep’s heart and sheep internal anatomy are very similar to a human, so it gives us an opportunity to learn more about what a human heart might look like on the inside. By dissecting into a heart, we can see each different section in detail and can learn how each section helps in pumping blood around the body.

- The value of pigs may rise if demand increases for their organs (Thinkstock)

What heart is similar to a human heart?
