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.
The base of the heart is the part of the border of the heart that is located opposite the apex. It involves the left atrium, to a smaller extent the right atrium, and the parts of the great vessels nearest to the heart.
