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.
