The heart is divided into four chambers. The two upper chambers are called atria (Singular : atrium) and the two lower chambers are called the ventricles. The partition between the chambers helps to avoid mixing up of blood rich in oxygen with the blood rich in carbon dioxide.
The right side of the heart is completely separated from the left side with the help of a partition called septum so that the two types of blood do not mix. The heart has a number of valves that allow the blood to flow in one direction only.
