The upper chamber is called an atrium (or auricle), and the lower chamber is called a ventricle. The two atria act as receiving chambers for blood entering the heart; the more muscular ventricles pump the blood out of the heart.
The human heart is divided into 4 chambers or parts: the two ventricles (lower parts) and two atria (upper parts). The heart plays an important role in blood circulation, by pumping deoxygenated blood into the lungs, and supplying oxygenated blood from the lungs to other parts of the body.
