Question

Quizplus · Accepted Answer

The cardiac notch is a concave groove on the anterior surface of the left lung that allows space for the heart to fit. It is located on the medial surface of the lung and is specifically designed to accommodate the heart, which sits tilted to the left side of the body. Therefore, the heart indents into the cardiac notch of the left lung. The oblique fissure divides the lungs into lobes, the hilum is the entry/exit point of nerves and blood vessels, the apex of the lung is the top, and the base is the bottom.
