A pig's heart is very similar to the human heart in that it has 4 chambers while an amphibian heart has only 3 chambers. The pulmonary system in an amphibian is low pressure and has only an atrium.
The main difference between a chicken and pig heart is their size. Pig hearts are larger and have a more complex structure than chicken hearts. Additionally, the muscle fibers and overall composition of the two hearts may differ slightly.
The difference between a heart and a human heart is one heart is a shape, and the other is the heart in our chest that pumps blood all throughout our body.
