Which of the following correctly describes the histological transition from bronchi into smaller branches in the bronchial tree?
A)The lining changes from respiratory epithelium to stratified squamous epithelium.
B)The rings of cartilage completely disappear during the transition from the trachea into the bronchial tree.
C)The amount of smooth muscle increases in the smaller passageways of the bronchial tree.
D)More hyaline cartilage is found in the smaller passageways of the bronchial tree.

Question

Quizplus · Accepted Answer

As the bronchi narrow into smaller branches in the bronchial tree, the amount of cartilage decreases while the amount of smooth muscle increases. This allows for greater control over the diameter of the smaller passageways, regulating airflow and resistance. The lining remains respiratory epithelium throughout the bronchial tree, and while there may be some variation in the amount of cartilage, it does not increase as the passageways become smaller. Stratified squamous epithelium is not found in the respiratory system.
