Which statement accurately describes the bronchial tree?
There are two secondary bronchi in the sight lung and three in the loft lung.
The right primary bronchus is more vertical and wider than the left.
The carina is only present in the left primary branches.
Inhaled air does not enter the terminal bronchioles.
The Correct Answer is B
A. There are two secondary bronchi in the right lung and three in the left lung: There are three secondary bronchi in the right lung and two in the left lung due to the number of lobes in each lung.
B. The right primary bronchus is more vertical and wider than the left: The right bronchus is more vertical and wider, making foreign objects more likely to enter the right lung.
C. The carina is only present in the left primary branches: The carina is located at the bifurcation of the trachea into the right and left bronchi, not just in the left.
D. Inhaled air does not enter the terminal bronchioles: Inhaled air flows all the way through the bronchial tree, including the terminal bronchioles.
