After studying the human body, I had extra time to study other systems, so I began to wonder what a dolphin's systems look like compared to our own systems. I studied the skeletal, muscular, nervous, cardioascular, and digestive systems of the dolphin, then compared them to what I already knew of a human's same systems. Throughout this presentation is my results and the comparisons that came from them.
