Question

Why do the walls of trachea donot collapse when there is less air in it?

Answer 1

The trachea has a series of C-shaped cartilage rings that run the length of it, down to where it bifurcates into the bronchi. ... The structure allows the contents of the esophagus to pass behind thetrachea and prevents it from collapsing as a result of pressure changes.
