There are three chambers. One collects blood from the body and pumps it into the middle chamber. This pumps blood both to the lungs and to another chamber which pumps the blood back through the body. The major difference between this and a human heart is the mixing of blood from the body and blood from the lungs. In humans the lungs have their own separate circulatory system and there is no mixing of blood. This is because humans are warm blooded and need more Oxygen than a cold blooded creature requires. Blood leaving the human heart is fully oxygenated. Fish, frogs and reptiles have blood which is just partially oxygenated, because of the mixing of blood in their hearts.
FYI: the human heart develops from a two chambered (fish) and then a three chambered (frog) design in the embryo. The middle chamber is eventually split into two chambers by a muscular sheet of tissue called a septum. One congenital defect is an incomplete development of this septum before birth. The infant is born with "hole in the Heart disease". The mixing of blood severely limits the Oxygen in the blood and these infants are also called "blue babies" because of their skin color. Open heart surgery was perfected decades ago and this condition can be corrected.

How do frogs and tadpole hearts differ?
Frogs have three-chambered hearts, consisting of two atria and one ventricle. Tadpoles, on the other hand, have a two-chambered heart with one atrium and one ventricle. As tadpoles undergo metamorphosis into frogs, their hearts change structure to support the shift from aquatic to terrestrial life.
Do all animals with two chambered hearts live in the water?
No, not all animals with two-chambered hearts live in the water. For example, some amphibians, like frogs, have two-chambered hearts and live both on land and in water.

What creature has 5 hearts?
I think the animal that has 4 hearts is a earthworm, because in my science class i dissected a earthworm, i saw 4 different parts of tiny black hearts as my teacher said they were, so yes i am learning in 7th grade but i did learn a lot about the earthworm including the hearts. so that proves that the animal that has 4 hearts is.... the earthworms.
