The '''apex of the heart''' is the lowest superficial part of the [[heart]].
It is directed downward, forward, and to the left, and is overlapped by the [[left lung]] and [[pleura]].
==External anatomy==
It lies behind the fifth left [[intercostal space]], 8 to 9 cm. from the [[mid-sternal line]], slightly medial to the [[midclavicular line]].
Alternately, it can be found about 4 cm. below and 2 mm. to the medial side of the left [[mammary papilla]].
