Lung diseases are a major specialty of the Thoracic and Endocrine Surgery Division, including cancers, infectious diseases, pneumothorax, bronchiectasis and emphysema. Lung surgery is one of the main focuses of the Division.
The lungs oxygenate blood that comes from the heart (upon inhalation) and expel carbon dioxide (upon exhalation). The action of the respiratory muscles on the lungs produces inhalation and exhalation.
The right lung is divided into three lobes: upper, middle and lower. The left lung only has two lobes: upper and lower. Each lobe is composed of several segments.
