Multiple Choice

Which of the following statements about the trachea is false?

The trachea is supported by C-shaped cartilaginous rings.

The trachea is primarily responsible for gas exchange in the lungs.

The trachea is lined with ciliated epithelium to help trap particles.

Verified step by step guidance

Identify the primary function of the trachea. The trachea serves as a passageway for air to move from the larynx to the bronchi, not for gas exchange.

Understand the structure of the trachea. It is supported by C-shaped cartilaginous rings that provide structural support and maintain an open airway.

Recognize the lining of the trachea. The trachea is lined with ciliated epithelium, which helps trap and expel particles and pathogens from the respiratory tract.

Examine the bifurcation of the trachea. The trachea divides into the left and right bronchi at a point called the carina, directing air into each lung.

Determine which statement is false by comparing each statement to the known functions and structures of the trachea. The statement that the trachea is primarily responsible for gas exchange is false, as gas exchange occurs in the alveoli of the lungs.
