Step 1To answer this question, I'll provide a detailed explanation of the anatomical differences between the right and left lungs.
Step 2: Anatomical Location and Space Constraints
The difference in lung lobes is directly related to the heart's position in the chest cavity. The heart is not perfectly centered but is slightly positioned towards the left side of the chest.
Final Answer
The right lung has three lobes, while the left lung has only two lobes due to the heart's position on the left side of the chest, which requires the left lung to be modified to create space for the cardiac structure.
