Location of the Heart. Heart is located safely inside the chest cavity which looks like a cage bound by the ribs and breast bone (sternum). The chest cavity is also called as thoracic cavity and it lies between neck and abdomen.
The sternum is located at the middle of the front part of the rib cage between the breasts. In women, the cleavage of the breasts (intramammary cleft) lies over the sternum. The location of the sternum has therefore contributed to the common term breastbone although it it not part of the male or female breast.
