The two hearts which supply blood to the gills are called branchial hearts. The more central heart is known as the systemic heart.
An octopus has three hearts. Two pump blood through each of the two gills, while the third pumps blood through the body.
Two of the hearts are located on the lateral sides, close to the gills. The third, systemic heart, is located on the midline (dorsal to the digestive gland).
A three chambered heart has two atria and one ventricle. Only amphibians and reptiles have three chambered hearts.
