Answer 1

tracheal cartilage is supported

Answer 2

C) bronchiole

Step-by-step explanation:

Rings of cartilage, similar to those of the trachea, support the structure of the bronchi and prevent their collapse. The primary bronchi enter the lungs at the hilum, a concave region where blood vessels, lymphatic vessels, and nerves also enter the lungs. The bronchi continue to branch into bronchial a tree.
