$ 3) Jeremiah was a bullfrog. You kept him for many years in an aquarium where he had
several spots he could crawl out of the water and sit for food. One spot was a mound of
earth in the left-hand corner, another was on a piece of wood in the middle of the tank
and the third was a rock in the right-hand corner. Over a five-day period you noted where
Jeremiah was sitting each time you left for school and again when you got home. Here's
what you found:

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
