Study Notes
Respiratory System Components
- Nostrils: Openings in the nose that allow air to enter the respiratory system.
- Mouth: Serves as an alternative pathway for air, known as the oral cavity.
Key Structures
- Larynx: Commonly referred to as the voice box, plays a crucial role in sound production.
- Lungs: Pair of saclike organs in the chest responsible for gas exchange (oxygen and carbon dioxide).
- Bronchi: Two main branches at the lower end of the trachea, directing air into each lung.
Airway Pathway
- Trachea: Also known as the windpipe, it serves as the main airway connecting the larynx to the bronchi.
- Bronchioles: The smallest branches of the bronchi, further distributing air throughout the lungs.
Respiratory Functions
- Diaphragm: A large, flat muscle at the base of the chest cavity that is essential for inhalation and exhalation.
- Alveoli: Microscopic air sacs with thin walls, where the exchange of oxygen and carbon dioxide occurs between air and blood.
Additional Structure
- Pharynx: The throat area that serves as a passageway for both air and food, connecting the nasal cavity to the larynx.
