THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The oblique and horizontal fissure divides the lungs into superior, middle and inferior lobes. Thus the right lung has three lobes while the left has two. Each lobe is supplied by a lobar bronchus.

Detailed explanation-2: -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.

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. The heart sits in the cardiac notch, which is a groove in the lower lobe.

Detailed explanation-4: -The left lung has only two formal lobes because of the space taken up in the left side of the chest cavity by the heart, though it does have the lingula, which is similar to a lobe.
