Unlabelled diagram of the heart

The vital importance of the heart is obvious. If one assumes an average rate of contraction of 75 contractions per minute, a human heart would contract approximately , times in one day, more than 39 million times in one year, and nearly 3 billion times during a year lifespan. Each of the major pumping chambers of the heart ejects approximately 70 mL blood per contraction in a resting adult. This would be equal to 5. Over one year, that would equal 10,, liters or 2. In order to understand how that happens, it is necessary to understand the anatomy and physiology of the heart. The human heart is located within the thoracic cavity, medially between the lungs in the space known as the mediastinum. Figure Within the mediastinum, the heart is separated from the other mediastinal structures by a tough membrane known as the pericardium, or pericardial sac, and sits in its own space called the pericardial cavity. The dorsal surface of the heart lies near the bodies of the vertebrae, and its anterior surface sits deep to the sternum and costal cartilages.

The right side pumps deoxygenated close deoxygenated Blood that is low in oxygen as cells have used it and high in carbon dioxide as cells have produced it. The left side pumps oxygenated close oxygenated Blood that is high in oxygen and low in carbon dioxide. This unidirectional flow of blood through the heart shows that mammals have a double circulatory system.
