This alligator is cold blooded. when it is cold, the alligator looks for a warm place to lay, like on the sand or a rock warmed by the sun. how does the sand or the rock warm the alligator? a) direct contact or conduction b) through the air or radiation c) by heating up the air around the alligator d) by transferring heat into the alligators blood    ( did it, it's a)

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.

what are the options? add them, then i will be glad to .
