How many lobes comprise the right lung in the human respiratory system?
Solution
Correct Answer: Option B
- The right lung in the human respiratory system is composed of three lobes: the superior, middle, and inferior lobes.
- These lobes are separated by two fissures – the horizontal fissure and the oblique fissure.
- This anatomical division allows for better expansion and efficient gas exchange during respiration.
In contrast, the left lung has only two lobes (superior and inferior) to accommodate the space taken by the heart.
Understanding the lobar structure of the lungs is essential for clinical practices such as diagnosing lobar pneumonia, lung cancer localization, and for surgical procedures.
Key points:
- Right lung has three lobes.
- Lobes are separated by horizontal and oblique fissures.
- Left lung has two lobes due to space constraints from the heart.
