ANATOMY

Detailed explanation-1: -The right and left lung anatomy are similar but asymmetrical. The right lung consists of three lobes: the right upper lobe (RUL), the right middle lobe (RML), and the right lower lobe (RLL). The left lung consists of two lobes: the left upper lobe (LUL) and the left lower lobe (LLL).

Detailed explanation-2: -The right lung consists of three lobes: the superior, middle, and inferior lobes. The left lung consists of two lobes: the superior and inferior lobes. A bronchopulmonary segment is a division of a lobe, and each lobe houses multiple bronchopulmonary segments.

Detailed explanation-3: -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-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.
