Detailed explanation-1: -The base of the heart is located at the level of the third costal cartilage, as seen in Figure 1. The inferior tip of the heart, the apex, lies just to the left of the sternum between the junction of the fourth and fifth ribs near their articulation with the costal cartilages.
Detailed explanation-2: -The base of the heart is probably better termed its posterior surface. It is not the most inferior surface of the organ but rather the most superior. It assumed the term because it is thought to resemble the base of the pyramid or cone which extends obliquely to the left to the apex of the heart.
