Full Answer

Frogs are amphibians that eat insects and small animals. There are about 4,740 different species of frogs found throughout the world, with 90 of those species are found in the United States. Frogs are found on every continent except Antarctica, but most are found in tropical climates. They live on land near swamps, ponds or in damp places. Frogs soak water in through their skin, and if their skin dries out they will die. They never close their eyes and can see forwards, sideways and upwards at the same time.

    How does a frog heart function?

    A:

    The frog heart has three chambers, two atria that take blood from the body and one ventricle to pump it out, according to the University of Wisconsin-La Crosse's Zoo Lab. It relies on spiral valves to move the blood to the right places. Because there is only one ventricle, there is some mixing of oxygenated and deoxygenated blood, but a groove through the ventricle helps minimize it.
