What is the function of left lung?
Each lung is divided into lobes—the left lung has two and the right lung has three—which are similar to balloons filled with sponge-like tissue. Each lobe receives air from its own branch of the bronchial tree, but they all have the same function: bringing oxygen into the bloodstream and removing carbon dioxide.
What is the size of a lung?
In the normal adult, the lungs weigh approximately 1000 g. Lung volume increases from about 250 mL at birth to 6000 mL in the adult. The height of a normal adult lung is 27 cm at total lung capacity, but in the range of normal breathing it is approximately 24 cm in height.

The right lung is larger and weighs more than the left lung. 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.
Why do we have 2 lungs?

Separation also decreases the chance of problems or disease in one spreading to the other.
