The Role of the Heart
The heart is described as the most valuable organ in the body. The function of the heart is to pump blood throughout the body. The heart works to pump and circulate all of the materials our body needs to operate properly. The right side of the heart receives de-oxygenated blood from the body. The blood rides through the Tricuspid Valve into the Right Ventricle. After that, it pumps through the Pulmonary Valve into the Pulmonary Artery. This is where the de-oxygenated blood is taken to the lungs to get oxygen.
