Final answer:
The trachea funnels air to the bronchi but does not mainly filter the air; this is done by the nose and nasal cavity.
Step-by-step explanation:
The statement that the trachea, or windpipe, filters the air we breathe and funnels it into the bronchi is false. While the trachea does funnel air into the bronchi, the primary role of filtering the air is performed by the nose and nasal cavity. The trachea is lined with mucus-producing goblet cells and ciliated epithelia which can trap particles and propel them toward the pharynx, but the bulk of the filtering occurs before air reaches the trachea.
