Question

Quizplus · Accepted Answer

The cardiac notch is a concave space on the medial aspect of the left lung, accommodating the space where the heart projects into the left hemithorax. This feature is not present on the right lung, nor does it relate to the origin of coronary arteries or the resting place of the pulmonary trunk on the heart.
