Circulatory System of an Eastern American Toad
-The circulatory system of the frog is similar to humans but they have only one ventricle in their heart instead of two.
-The heart is a pump that carries deoxygenated blood to the lungs and oxygenated blood from the lungs to the rest of the body.
-Since toads have only one ventricle, the blood flows from both atriums into one ventricle so it has both oxygenated and deoxygenated blood in it.
-The blood is then pumped from the aorta to the lungs or the body.
-The heart is specially made like this so that the toad has the ability to stay underwater longer.
-Frogs do not use their lungs underwater.
