The heart has four chambers: two chambers on the right portion and two chambers on the left. The two chambers belonging to the upper portion of the heart are called atria (atrium when referring to only one) while the chambers located at the lower part are called ventricles.
Oxygen-poor blood from the veins is received by the right side of the heart. The heart then pumps this blood to the lungs where it picks up oxygen and gets rid of carbon dioxide accumulated from other parts of the body.
From the lungs, the newly oxygenated blood goes back to the heart, entering through the left side this time. From there, the heart pumps the oxygen-rich blood through the arteries where it makes the journey to the other organs in the body that need it.
Congestive heart failure occurs when the heart can’t keep up with all the blood that needs to be pumped throughout the body.
