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.
Fish have 2 chambers, one atrium and one ventricle. Fish hearts draw in deoxygenated blood in the atrium, and pump it out through a ventricle. Blood enters the heart, gets pumped through the gills and the oxygenated blood goes out to the body. Amphibians and reptiles have 3 chambers: 2 atria and a ventricle.he above diagram is an action potential recorded in the ventricular cardiac cell of the heart. 4) Resting potentials in these cells is set by a large K+ permeability due to a combintation of the leak K+ channel and a voltage-gated K+ channel (called the inward rectifier K+ channel) that is open at rest.
