Anatomy & Physiology Respiratory #15

Question

Which structure is found exclusively in the right lung of the respiratory system?

Answers

  1. Middle lobe
    • Rationale:

      The right lung has three lobes; therefore, the middle lobe is a structure of the respiratory system that is found exclusively in the right lung.

  2. Inferior lobe
    • Rationale:

      The right and the left lungs both have an inferior lobe; therefore, this lobe is not exclusive to only the right lung.

  3. Superior lobe
    • Rationale:

      The right and the left lungs both have a superior lobe; therefore, this lobe is not exclusive to only the right lung.

  4. Oblique fissure
    • Rationale:

      Both the right and the left lungs contain oblique fissures. The fissure on the left lung separates the superior lobe from the inferior lobe while the fissure on the right lung separates the superior and middle lobes from the inferior lobe.

Overview

There are two lungs in the lower respiratory tract, the right lung and the left lung.

Explanation

Learning Outcomes

Each lung is divided into lobes. The right lung has three lobes while the left lung has two lobes. The three lobes of the right lung include the superior lobe, the middle lobe, and the inferior lobe, while the two lobes of the left lung include the superior lobe and the inferior lobe.

Test Taking Tip

Consider each structure of the lung when determining the correct answer choice for this question.
