4. Which of the following does not make up a bronchi? a. cartilage
c. smooth muscle
b. mucous lining
d. pleural membrane

Explanation:

The cartilage and mucous membrane of the primary bronchi are similar to that in the trachea. As the branching continues through the bronchial tree, the amount of hyaline cartilage in the walls decreases until it is absent in the smallest bronchioles. As the cartilage decreases, the amount of smooth muscle increases.
