Question

2 what is the importance of the cartilage rings in the trachea? 1 points 00:09:03 multiple choice they allow for the passage of swallowed food through the trachea. they keep the trachea from collapsing when you inhale. they form the mucociliary escalator that helps sweep debris from the lungs. they produce mucus that traps any debris that may be inhaled.

Explanation:

The trachea is a tube that carries air to the lungs. Cartilage rings are C - shaped structures. When we inhale, the pressure inside the trachea changes. The cartilage rings provide structural support. If there were no cartilage rings, the trachea could collapse due to the negative pressure during inhalation.

• Option 1: Swallowed food passes through the esophagus, not the trachea. So this option is incorrect.
• Option 2: As explained above, cartilage rings keep the trachea open (prevent collapse) during inhalation. This is correct.
• Option 3: The mucociliary escalator is formed by ciliated cells and mucus - secreting cells (not cartilage rings). So this option is incorrect.
• Option 4: Mucus is produced by goblet cells (not cartilage rings). So this option is incorrect.

Answer:

They keep the trachea from collapsing when you inhale.
