By 1828 Randolph was back in Georgia's good graces, and the state legislature decided to name another new county for him. Monticello, Jasper's county seat, pays tribute to Thomas Jefferson, using the name of his home.
An octopus has three hearts, nine brains, and blue blood. Two hearts pump blood to the gills, while a third circulates it to the rest of the body. The nervous system includes a central brain and a large ganglion at the base of each arm which controls movement.
In the 3 chambered heart, a single ventricle pumps both out of the heart, and there is some mixing between fresh and old blood. The 2 ventricle-4 chamber heart prevents mixing allows the blood leaving the heart to have far more oxygen than it would otherwise. But just like an 8 cylinder engine put out a lot more horsepower than a 4 cylinder, so does a 4 chamber (2 pairs) heart have a much more power to supply the body with energy and oxygen-rich blood than a 3 chamber (1 ventricle) heart. 2  There is a huge advantage to having a 4 chamber heart.
