Before we go further into fish circulation, let's compare a human with a fish to get a perspective on the anatomy and function. In mammals (like us) there is a double circulation. The right side of the heart receives blood returning back from the body; this blood is low in oxygen (blue in the figure to the right).The fish circulation. As seen on the previous page, the major difference between the mammalian and fish circulatory system. The fish heart needs to generate the driving pressure for both the gills (lungs in mammals) and the body since they are connected in series, as seen in the figure to the left. circulatory system of fish heart
