The left upper lobe contains which features?

Explanation:
The left upper lobe specifically contains the lingula, a tongue‑like projection on the anteromedial side that serves as a left‑sided counterpart to the right middle lobe, and it also sits near the cardiac notch, the indentation along the anterior border where the heart sits against the lung. The left lung has only two lobes, upper and lower, separated by the oblique fissure, and there is no middle lobe on the left. So the combination of the lingula and the cardiac notch is characteristic of the left upper lobe.
