    The Apex lies under the fifth intercostal space, TIFO INCHES BELOW the nipple (in the male) and HALF AN INCH TO THE RIGHT of the left mam- millary line. The Right Margin corresponds with a line beginning on the third costal cartilage half an inch to the right of the right sternal line, curving slightly to the right and downward to the end of the sternum. The Left Margin corresponds with a line Ijeginning on the third costal cartilage an inch to the left of the left sternal line, curving to the left and downward to the apex beat, but not including the nipple. The Lower Margin corresponds nearly with a line join- ing the apex and the end of the sternum. RELATION of the heart to the lung in front. It is Covered by the lung (Gardiac dulness) from the upper margin of the third to the lower margin of the fourth rib, and below the fourth rib between the para- sternal line and the left margin of the heart. It is Uncovered by the lung {cardiac flatness) in the tri- angular or irregularly quadrilateral area bounded on the right by the meso-sternal line, on the left and above by a line drawn from the fourth costal cartilage to a point a little to the right of the apex beat. VALVES of the heart. Position (Gray). semilunah valves. THE PULMONIC valve lies behind the left sternal line at the level of the third costal cartilage. THE AORTIC valve lies close to the left sternal line, behind the third intercostal space. auriculo-ventricular valves. THE TRICUSPID valve lies behind the meso-sternal line about the level of the fourth costal cartilage.
