How many lobar bronchi are present in the right lung?

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

Answer: (B)

The right lung contains three lobar bronchi, which correspond to its three lobes: the upper lobe, middle lobe, and lower lobe. Each lobe receives its own lobar bronchus, which is an important feature of the bronchial tree's anatomy. This structure allows for efficient distribution of air to each lobe for optimal gas exchange during respiration. The left lung, in contrast, has only two lobes (upper and lower), and therefore has two lobar bronchi. Recognizing this anatomical distinction is crucial for understanding respiratory physiology and conditions that may affect lung function.
