What is the primary function of the trachea in animals?

  1. Transport food to the stomach

  2. Serve as a passage for air to the lungs

  3. Filter toxins from the blood

  4. Regulate body temperature

The correct answer is: Serve as a passage for air to the lungs

The primary function of the trachea in animals is to serve as a passage for air to the lungs. This cylindrical tube is an essential part of the respiratory system, connecting the throat (pharynx) to the bronchi, which lead into the lungs. The trachea is lined with cilia and mucus, which help to trap particles and pathogens, ensuring that the air reaching the lungs is cleaner and free from harmful substances. This structure allows for the efficient flow of air during inhalation and exhalation, playing a crucial role in gas exchange and overall respiratory function. In contrast, the other options represent different physiological functions that do not relate to the trachea's role in the respiratory system. The transport of food, filtering of toxins, and regulation of body temperature are managed by other organ systems and structures in the body.
