called the systemic heart. Here’s a brief explanation of the function of each heart:
Two Branchial Hearts:
The branchial hearts are responsible for pumping blood through the gills, where oxygen is extracted from water and carbon dioxide is released. Each branchial heart is located near a gill, and they help facilitate the oxygenation of the octopus’s blood.
One Systemic Heart:
The systemic heart pumps the oxygenated blood to the rest of the body. After the blood is oxygenated in the gills, it is collected and pumped by the systemic heart to supply oxygen to the octopus’s organs and tissues.
The unique circulatory system of octopuses is adapted to their marine environment and high metabolic rates. The presence of three hearts helps ensure efficient oxygenation and distribution of blood throughout the octopus’s body.
