How many lobes does the right lung contain?

The right lung contains three lobes, which are divided into the upper, middle, and lower lobes. This anatomical structure allows for greater surface area for gas exchange compared to the left lung, which only has two lobes (the upper and lower) due to the presence of the heart on the left side of the thoracic cavity.

Each lobe of the lung is separated by fissures, helping to optimize the lung’s function in respiration, and the right lung is slightly larger than the left lung. Understanding this anatomical difference is crucial in emergency medical situations, as it can impact respiratory assessments and interventions.
