Do both lungs have 3 lobes?
Each lung is separated into lobes branching off the main bronchus; the right lung has three lobes, while the left has only two lobes. As the bronchi branch out, the total area of the two new branches is larger than its parent bronchus, making it extremely easy for the air to rush into the lungs.
What is the function of lung lobes?
Each lobe of the lung has the same physiologic function, bringing oxygen into the bloodstream and removing carbon dioxide. Sections of a lobe, or even entire lobes can be removed as a treatment for conditions such as lung cancer, tuberculosis, and emphysema.
What is the function of the lung?
The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

Can a person with hyperexpanded lungs fully exhale?
A person with hyperexpanded lungs cannot fully exhale, which leaves air trapped inside the lungs. Is This an Emergency? If you are experiencing serious medical symptoms, seek emergency treatment immediately. People with hyperexpanded lungs can exhale only a small percentage of air with each breath they take.
