Choose distinguishing characteristics of the trachea: - The trachea lacks cartilage, so it easily collapses. - The trachea has an abundance of smooth muscle and changes its diameter to close easily. - The trachea has strong cartilage that overlaps a bit to allow space for the esophagus to send food along.

What is the trachea? The trachea is a tube through which air moves. It is a flap of tissue that seals off the windpipe and prevents food from entering. It also contains the voice box, which houses the vocal cords and allows for the passage of air. The trachea serves as a passage for food to the esophagus and air to the larynx.
