WebbThe nervous system functions in communication between the various parts of an organism and between the organism and its external environment. It consists of the central nervous system; the brain and spinal cord, and the peripheral nervous system; the sense organs, cranial and spinal nerves, and their branches. Shark Cranial Cavity. 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…
