Answer:
The heart is located inside the thoracic cavity, medially between the lungs in the mediation. It is about the size of a fist, is wide at the top and narrows towards the base.
Explanation:
Its center is about 1.5 cm to the left of the middle sagittal plane. Located on the heart are the great vessels: the superior and inferior vena cava, the pulmonary artery and vein, as well as the aorta. The aortic arch is behind the heart. The esophagus and spine are further behind the heart.
The heart is separated from the other mediastinal structures by a resistant membrane known as pericardium, or pericardial sac, and is located in its own space called the pericardial cavity.
