Question 9

The heart lies obliquely (at an angle) in the mediastinum, with its base directed posteriorly and slightly superiorly and its apex directed anteriorly and slightly inferiorly. The apex is also directed to the left, so that approximately two-thirds of the heart’s mass lies to the left of the midline of the sternum (figure 12.3a). The base of the heart is located just behind the sternum and extends to the space just below the second rib, called the second intercostal space. The apex is just behind the 5th and 6th ribs at the 5th intercostal space and just to the left of the sternum. If you draw an imaginary line straight down from the middle of your left clavicle, it will pass over the apex. This perpendicular line is called the midclavicular line (figure 12.3b).
