American Zoologist. 17: p. 411-429.[1] Sharks possess a single-circuit circulatory system centered around a two-chambered heart. Blood flows from the heart to the gills where it is oxygenated. This oxygen-rich blood is then carried throughout the body and to the tissues before returning to the heart. As the heart beats, deoxygenated blood enters the sinus venosus. The blood then flows through the atrium to the ventricle, befor… polyurethane dispersion coating
