Which term refers to the Right Upper Lobe?

• A. Right Lower Lobe
• B. Right Upper Lobe
• C. Left Lower Lobe
• D. Left Upper Lobe

Answer: (B)

Lung lobes are named by their position on each side. The right lung has three lobes: upper, middle, and lower. The term that designates the top part of the right lung is Right Upper Lobe. It sits in the superior region and is separated from the middle lobe by the horizontal fissure and from the lower lobe by the oblique fissure. This lobe includes segments like apical, anterior, and posterior. The other options point to different lobes—the right lower lobe is the bottom right, the left upper lobe is the top left, and the left lower lobe is the bottom left.
