The heart is contained within the thoracic cavity, specifically in a space known as the mediastinum. It is surrounded by a protective sac called the pericardium, which consists of two layers: the fibrous pericardium and the serous pericardium. This arrangement helps to anchor the heart, reduce friction during its movement, and provide a barrier against infection. The heart is located between the lungs and is positioned slightly to the left of the midline of the body.
