ID & Transcript: Anirban is wearing a blue button-up shirt standing in front of a tan wall. He signs as text and octopus graphics appear: Octopuses have 1, 2,… three! hearts: Their two peripheral hearts pump blood through the gills, where it picks up oxygen. A central heart then circulates the oxygenated blood to the rest of the body to provide energy for organs and muscles. Does the blood go back to the central heart? Nope! The blood then goes to the peripheral hearts to push out carbon dioxide. Very interesting!
