The heart is located in the thorax, within the mediastinum, slightly to the left of the midline.

Explanation:
The heart sits in the central chest space called the mediastinum, inside the thoracic cavity, and it is positioned slightly to the left of the body’s midline. The mediastinum holds the heart and great vessels between the two lungs. The heart’s apex points to the left, and most of its mass lies to the left of the sternum, with the base oriented toward the right and posteriorly. This arrangement makes sense because the heart is nestled between the lungs but not within the lung tissue, and it is clearly not in the abdomen. So the statement is true.
