How many lobes does the right lung have?

The right lung consists of three lobes: the superior lobe, the middle lobe, and the inferior lobe. This anatomical structure is important for understanding respiratory mechanics and pathologies. Each lobe is separated by fissures that allow for independent movement and expansion during breathing. The presence of three lobes on the right side contrasted with the two lobes on the left helps accommodate the heart, which is positioned slightly to the left of the chest cavity. Understanding the structure of the lungs is vital for perfusionists, as it directly relates to lung function, gas exchange, and the implications for heart-lung machines during surgery.
