Shark anatomy - Wikipedia
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.
SHARK HEART AND CIRCULATORY SYSTEM - Enchanted Learning
SHARK HEART AND CIRCULATORY SYSTEM. Sharks have a two-chambered heart, with an atrium (also called the auricle) and a ventricle. The heart is an S-shaped tube that is located in the head region of the shark.

The shark heart is composed of four compartments, arranged in an S-shape and separated by valves. The first and second compartments (sinus venosus and auricle, respectively) are bulbous and thin-walled, the first containing a biological pace-maker which dictates the heart's contraction rate, the second acting as a blood-collecting chamber.

Shark Circulatory System: The Heart of the Ocean’s Apex Predator
A shark’s circulatory system diagram shows how blood moves through its body. The heart pumps blood to the gills, where it gets oxygen. Then, the blood travels to the rest of the body. Understanding this flow helps us learn how sharks survive in the ocean. Key features to note in a shark circulatory system diagram
