The Heart's Anatomy

The weight of the heart is between 7 and 15 ounces and is a little bigger than the size of your fist. The location of the heart is between the lungs in the center of the chest. The membrane that surrounds the heart is called the pericardium. The heart consists of four chambers. The left and right atria are known as the upper chambers. The lower chambers are referred to as the left and right ventricles. The septum is the wall of muscle that divides the left and right atria and left and right ventricles. The strongest chamber of the heart is the left ventricle.

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.
