The heart is the center of the circulatory system. It provides oxygen to the body and removes carbon dioxide and waste. It is made up of two pumps. One pump, the right side, provides blood to the lungs and the other, left side, provides blood the rest of the body. The right side pumping blood to the lungs is called pulmonary circulation; the left side is coined systemic circulation (Huether & McCance, 2017). Arteries carry blood from the heart to other parts of the body. Veins carry blood back to the heart. The atria and ventricles are separated by an electrical framework that allows them to beat in synchrony (Hammer & McPhee, 2014). The beginning of the of the cardiac cycle starts with the left atrium contracting and forcing blood into the left ventricle. From there blood is forced into the aorta and the left ventricle relaxes (Hammer & McPhee,2014). Diastolic is the measure of the pressure of the heart at rest.
