Question

All of the following statements accurately compare branches of the bronchial tree except a. The tertiary bronchi contain a slight amount of supportive tissue, whereas the bronchioles contain no cartilage at all. b. The primary bronchi have cartilaginous rings, whereas the secondary bronchi have irregular plates of hyaline cartilage.

Answer 1

The tertiary bronchi contain a slight amount of supportive tissue, whereas the bronchioles contain no cartilage at all. The primary bronchi have cartilaginous rings, whereas the secondary bronchi have irregular plates of hyaline cartilage.

Step-by-step explanation:

The tertiary bronchi contain a slight amount of supportive tissue and the bronchioles contain no cartilage at all. The primary bronchi have cartilaginous rings, whereas the secondary bronchi have irregular plates of hyaline cartilage. Therefore, statement (a) is incorrect, as the bronchioles do not contain any cartilage.

Answer 2

The incorrect statement about the bronchial tree is that tertiary bronchi contain a slight amount of supportive tissue, whereas bronchioles contain no cartilage at all.

Step-by-step explanation:

The statement that does not accurately compare branches of the bronchial tree is: "The tertiary bronchi contain a slight amount of supportive tissue, whereas the bronchioles contain no cartilage at all." The accurate comparison is that both the primary and secondary bronchi have cartilaginous structures, but they differ in form. The primary bronchi have cartilaginous rings, whereas the secondary bronchi contain irregular plates of hyaline cartilage.

As for tertiary bronchi and bronchioles, tertiary bronchi have supportive tissue with cartilage, while bronchioles lack cartilage altogether, and their walls are composed of smooth muscle and elastic fibers.
