- Larynx
- Trachea
- Right main bronchus
- Left main bronchus
- Right lung

3) Find the parts of the Respiratory System
- Nasal cavity
- Pharynx
- Larynx
- Trachea
- Bronchus
- Bronchiole
- Alveoli
- Diaphragm

- Lung

4) Select one or two parts and describe what they are used for in the Respiratory System.
- Trachea: The trachea, also known as the windpipe, is a tube that connects the larynx to the bronchi of the lungs. It allows air to pass through to the lungs for oxygen exchange.
- Alveoli: Alveoli are tiny air sacs in the lungs where gas exchange occurs. Oxygen from inhaled air passes into the bloodstream, and carbon dioxide from the blood is released into the alveoli to be exhaled.
