Chey Seamon’s STEAM project analyzes the evolution of the human heart, and its relation to a fish’s cardiac system. In Seamon’s art demonstration, she has created two separate models. One of a fish heart, or gills, and one of a human heart. In the photo, there are labels comparing the two, such as the connections of the aorta of the human heart and where they circulate blood to and from in the body. All in all, they’re great diagrams! The human heart consists of two major ventricles, the left and the right, whereas the fish only functions with one current that operates in a singular direction. The most obvious difference in the evolutionary changes of the heart lies in the sheer difference of blood flow, given that the two ventricles in the human heart work in tandem to pulse blood throughout the body, with pulmonary and systemic circulation, while the fish heart relied on the gills and systemic capillaries to do all of the processing via only systemic circulation. Gas exchange occurs directly in the gills for fish, while in humans, we perform this task in the lungs. Fish also only have two heart chambers, the atrium and the ventricle, while the human heart has four, the right and left atrium and the right and left ventricle, which also allows for a difference in blood volume going through the heart.
