Question

In humans, the lungs are divided into separate lobes. Which of the following option correctly represents the number of lobes in the right lung and the left lung respectively?

• A. 4, 2
• B. 4, 3
• C. 3, 2
• D. 4, 1

Answer 1

The correct option is C 3, 2

Lobation in lungs varies greatly from species to species. In humans, the right lung is divided by one horizontal and one oblique fissure into 3 lobes namely the superior (upper) lobe, the middle lobe, and the inferior (lower) lobe. The left lung has only one oblique fissure which divides it into 2 lobes i.e. the superior (upper) lobe and the inferior (lower) lobe.
