Answer:

2. the trachea widens and lengthens.

Explanation:

Moist, smooth tissue called mucosa lines the inside of the trachea. The trachea widens and lengthens slightly with each breath in, returning to its resting size with each breath out.

if your trachea is constricted or narrowing that is a sign of issue. normally it is very flexible and moves accordingly to what you’re doing
