Verified step by step guidance

Step 1: Begin by identifying the trachea's anatomical location and its role in the respiratory system. The trachea is a tube-like structure that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

Step 2: Understand the division of the respiratory tract into two main parts: the upper respiratory tract (which includes the nose, nasal cavity, pharynx, and larynx) and the lower respiratory tract (which includes the trachea, bronchi, bronchioles, and lungs).

Step 3: Compare the trachea's location to the structures of the upper respiratory tract. Since the trachea is located below the larynx, it is not part of the upper respiratory tract.

Step 4: Confirm that the trachea is part of the lower respiratory tract, as it is anatomically situated between the larynx and the bronchi, which are components of the lower respiratory system.

Step 5: Conclude that the trachea is part of the lower respiratory tract, and review the distinction between the upper and lower respiratory tracts for better understanding.
