Answer:
In the mediastinum
Step-by-step explanation:
It is located in the central region of the thorax, in the middle and lower mediastinum, between the two lungs, slightly to the left side. It is surrounded by a thick fibrous membrane called pericardium. The heart is protected inside the body by the rib cage. The ribs form the rib cage that connects the spine in the back and the sternum in the front. In very rare cases the heart leans to the right side. It is a clinical condition called dextrocardia and is congenital in nature.
