Why do animals have two chambers of heart?

The organization of these chambers will differ depending on the needs of the system, particularly as it relates to breathing and respiration. Animals with 2-chambered hearts are those that use gills to replenish oxygen in the blood supply, whereas animals that have 3- or 4-chambered hearts also contain lungs for respiration.

Which is the strongest Chamber of the heart?

The left ventricle is the strongest chamber of the heart. It pumps oxygen-rich blood to the rest of the body. The flow of blood into the heart, within the heart chambers and from the heart is guarded by the four valves present in the heart. The heart gets its nutrients and oxygen via the coronary arteries that run along the surface of the heart.

Each ventricle is located below an atrium.
