How many lobes does the right lung have?

• A. Two
• B. Three
• C. Four
• D. One

Answer: (B)

The right lung is comprised of three distinct lobes: the superior lobe, the middle lobe, and the inferior lobe. This anatomical structure allows for increased surface area for gas exchange, making the right lung somewhat larger and broader than the left lung, which has only two lobes (the superior and inferior lobes). Each lobe is separated by fissures – the horizontal fissure separates the superior and middle lobes, while the oblique fissure separates the middle and inferior lobes. Understanding the lobular anatomy of the lungs is crucial for interpreting radiographic images and diagnosing pulmonary conditions.
