The four valves of the heart prevent blood from flowing in the wrong direction, and open or close each time the heart beats. Learn more about them, here.

Learn about the anatomy of the heart and how its chambers, valves, and vessels work together to maintain effective blood circulation throughout the body to sustain life.

The chambers of the heart operate as a ‘double-pump’ system for the body’s circulation. In coordination with valves, the chambers work to keep blood flowing in the proper sequence.

The heart beats around 100,000 times a day, pumping approximately 8 pints of blood throughout the body 24/7.This delivers oxygen- and nutrient-rich blood to tissues and organs and carries away waste.
