on the mediastinal side of the left lung we find the impression
A
superior vena cava
B
arch of the aorta
C
inferior vena cava
D
azygos vein
Explanation: 

Detailed explanation-1: -Since the heart tilts to the left, the left lung is smaller than the right and has an indentation called the cardiac impression to accommodate the heart. This indentation shapes the inferior and anterior parts of the superior lobe into a thin tongue-like process called the lingual.

Detailed explanation-2: -The apex lies above the first rib. The three borders include the anterior, posterior, and inferior borders. The anterior border of the lung corresponds to the pleural reflection, and it creates a cardiac notch in the left lung. The cardiac notch is a concavity in the lung that formes to accommodate the heart.
