Lumen
The cavity on the medial surface of the left lung that accommodates the contents of the mediastinum is known as the cardiac notch. This indentation allows space for the heart, which is located slightly to the left of the midline in the thoracic cavity. The cardiac notch is a prominent feature that distinguishes the left lung from the right lung, which does not have a similar indentation.
