It has a similar shape, structure, chambers and valves.
Because their circulatory system is very similar to ours. Also, the size of our hearts are very close.
The heart of a sheep is bigger than humans and is positioned slightly differently in the body. Also, instead of having pulmonary arteries and veins they have what's called a pulmonary trunk and the top middle of the heart.
There are 2 valves in a sheep's heart. They are the mitral and tricuspid valve. The sheep also has a 4 chamber heart that is very similar to a human heart.
A sheep heart has four chambers.
If you look at the back wall of a fetal pig heart, you will see a vessel that is large in size in a sheep compared to the small size of the fetal pig heart. In sheep, the hemiazygous vein develops a connection to the heart through what becomes the superior vena cava.
As it is similar in structure to human hearts and they are readily available whereas most humans are buried with their hearts.
Sheep C would be the most genetically similar to sheep D, as they both share a common ancestor more recently compared to sheep A and B. This implies that sheep C and D would have a higher level of genetic relatedness.
it is very similar because of the sheep

Sheep hearts have a layer of fat surrounding them to provide insulation and protection for the heart muscle. This fat helps regulate the temperature and cushion the heart from physical damage. Additionally, fat is a source of energy that can be used by the heart for metabolic processes.
The muscle of a sheep's heart is thick for the same reason our heart muscle is thick. It is thick as it has to pump blood around the body, and so it is under a lot of pressure.
