Detailed explanation-1: -In anatomy, the precordium or praecordium is the portion of the body over the heart and lower chest. Defined anatomically, it is the area of the anterior chest wall over the heart. It is therefore usually on the left side, except in conditions like dextrocardia, where the individual’s heart is on the right side.

Detailed explanation-2: -Your mediastinum is a space in your chest that holds your heart and other important structures. It’s the middle section of your thoracic cavity, between your left and right pleural cavities (which hold your lungs).

Detailed explanation-3: -The pericardial membrane and the heart wall share the epicardium. The membrane that directly surrounds the heart and defines the pericardial cavity is called the pericardium or pericardial sac. It also surrounds the “roots” of the major vessels, or the areas of closest proximity to the heart.

Detailed explanation-4: -Your heart is located between your lungs in the middle of your chest, behind and slightly to the left of your breastbone (sternum). A double-layered membrane called the pericardium surrounds your heart like a sac.

Detailed explanation-5: -The heart is located directly behind the sternum, between the lungs. When talking about an anatomical structure that appears behind another anatomical structure of the body, the word posterior is used. Therefore, the heart is posterior to the sternum.
