Question

which statement describes the trachea?
multiple choice
it is comprised of c - shaped cartilage rings.
it contains no air - filtering mechanisms.
it is lined with simple squamous epithelium.
it is a passageway for food and for air.

Explanation:

The trachea is made up of C - shaped cartilage rings. These rings provide structural support while allowing the trachea to expand and contract. The trachea does have air - filtering mechanisms (such as cilia and mucus). It is lined with pseudostratified ciliated columnar epithelium, not simple squamous epithelium. The pharynx is a passageway for both food and air, not the trachea.

Answer:

It is comprised of C - shaped cartilage rings.
