Sea Turtle
Sea turtles unlike humans have a three chambered heart. The heart consists of the left auricle, the right auricle and the ventricle. The ventricle is separated by a partial septum which helps to minimize the mixing of deoxygenated and oxygenated blood.The deoxygenated blood flows into the right ventricle then it goes into the ventricle and into the lungs. While the blood is in the lungs it receives oxygen, then the blood goes into the left auricle and into the ventricle and let out to the body
