Human Heart Quiz – The Tireless Pump

The heart is a muscular organ about the size of a fist that pumps blood around the body. It has four chambers: two atria that receive blood and two ventricles that pump it out. Valves keep blood flowing in one direction.

The right side sends blood to the lungs to collect oxygen, and the left side pumps oxygen-rich blood to the rest of the body. A small group of cells called the sinoatrial node sets the rhythm with electrical signals.

A healthy heart beats about 100,000 times a day. Exercise, a balanced diet, not smoking and managing stress help keep it strong. Doctors can check heart health with blood pressure readings, ECGs and scans.
