The Cardiovascular System (Also known as the Circulatory System) of the California Sea Hare is an open circulatory system. The heart is located I the anterior part of the visceral mass. It also has two chambers the auricle and the ventricle. The auricle receives haemolymph from the gill. The ventricle pumps the haemolymph into the aorta. Then the aorta delivers the haemolymph to open arterial sinuses where it bathes and oxygenates the tissue. Then the haemolymph drains into a large venous sinus within the head and foot. Then it passes through vessels in the gills, and finally it returns to the heart.
One cool fact about the Circulatory system is that in some cases their is a second heart in the body of the Sea Hare.
