Document Summary
The cardiovascular (cv) system consists of the heart (a muscular pump), and the blood vessels. The precordium is the area on the anterior chest overlying the heart and great vessels. The heart and the great vessels are located between the lungs in the middle third of the thoracic cage (in the area called the mediastinum). The heart extends from the levels of the second to the fifth intercostal spaces and from the right border of the sternum to the left midclavicular line. Inside the body, the heart is positioned so that its right side is anterior and its left side is mostly posterior. Cardiovascular system: of the heart"s four chambers, the right ventricle is immediately behind the sternum and forms the greatest area of anterior cardiac surface. The left ventricle lies behind the right ventricle and forms the apex and slender area of the left border.
