Answer:
In the trachea, or windpipe, there are tracheal rings, also known as tracheal cartilages. Cartilage is strong but flexible tissue. The tracheal cartilages help support the trachea while still allowing it to move and flex during breathing

Answer:
Option 1 is correct Both (A) and (R) are correct and (R) is the correct explanation of the (A).
Explanation:
The rings in the trachea are made up of hyaline cartilage. These are incomplete for the short dorsal distance. The trachealis muscle covers the loose connective tissue which is present in the dorsal space, and attaches to the external tracheal rings’ surface.
These tracheal rings prevent the throat from collapsing when there is a low amount of air present or excessive air required during higher physical activities.
