Final answer:

Explanation:

Location of the Heart

The human heart is located within the thoracic cavity, medially between the lungs in the space known as the mediastinum. Within the mediastinum, the heart is separated from other structures by a tough membrane known as the pericardium. This area not only houses the heart but also contains great vessels such as the aorta and pulmonary trunk, which are attached to the superior surface of the heart known as the base.

The base of the heart is located at the level of the third costal cartilage, while the inferior tip, known as the apex, lies just to the left of the sternum at the junction of the fourth and fifth ribs. Understanding the precise location of the heart within the mediastinum is crucial for medical practices such as auscultation.
