Final answer:
The left lung has 2 lobes and 1 fissure, a cardiac impression, but not an esophageal depression or a cardiac notch.
Step-by-step explanation:
The left lung has 2 lobes and 1 fissure and a cardiac impression, but it does not have an esophageal depression or a cardiac notch. The right lung is slightly larger and has 3 lobes, while the left lung is slightly smaller and has 2 lobes.
The cardiac impression is a hollow on the surface of the left lung where the heart sits, and the cardiac notch is an indentation on the surface of the left lung that accommodates the heart. The esophageal depression is a feature of the right lung that allows space for the esophagus.
