MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -The left lung is slightly smaller and has a notch to give room for the heart. 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.

Detailed explanation-3: -Structure. Each lung is divided into lobes (sections): The right lung has 3 lobes and is slightly larger than the left lung. The left lung has 2 lobes.

Detailed explanation-4: -There is also a structural advantage to having the lungs be separate, the main one being that the bronchial tubes bifurcate naturally, and that there is a place for the heart and other “indivisible” organs in the middle. Separation also decreases the chance of problems or disease in one spreading to the other.
