Question

the right lung has __________ lobes; the left lung has __________ lobes.
multiple choice
three; three
three; two
two; two
two; three

Explanation:

The right lung has three lobes (superior, middle, and inferior), while the left lung has two lobes (superior and inferior). This is due to the space occupied by the heart on the left side, which reduces the space available for the left lung, resulting in fewer lobes.

Answer:

three; two (corresponding to the option "three, two")
