The respiratory system is a complex network of organs and tissues responsible for taking in oxygen and expelling carbon dioxide. The main components include:

1. **Nose and Nasal Cavity**: Filters, warms, and moistens air as it is inhaled.

2. **Pharynx (Throat)**: Serves as a pathway for the movement of air from the nose and mouth to the larynx.

3. **Larynx (Voice Box)**: Contains the vocal cords and is responsible for producing sound; also directs air into the proper channels.

4. Trachea (Windpipe): Connects the larynx to the bronchi and provides a clear airway for air to enter and exit the lungs.

5 Lungs: The primary organs of respiration, containing alveoli where gas exchange occurs.
