To identify the structures that are part of the lower respiratory tract, we first need to understand the distinction between the upper and lower respiratory tracts.

Structures of the Lower Respiratory Tract:

1. Bronchioles - These are smaller branches of the bronchi and are part of the lower respiratory tract.
2. Alveoli - Tiny air sacs where gas exchange occurs, they are also part of the lower respiratory tract.
3. Lungs - Organs that house the alveoli and are responsible for breathing and gas exchange.
4. Trachea - The trachea is the windpipe that connects the larynx to the bronchi; it is also considered part of the lower respiratory tract.

Structures Not Part of the Lower Respiratory Tract:

• Pharynx - This is part of the upper respiratory tract.
