Study Notes
Ventilation in the Respiratory System
- The primary function of ventilation is to facilitate the exchange of oxygen and carbon dioxide between the atmosphere and the lungs.
Gas Transfer
- The transfer of gases to and from the blood occurs in the alveoli, tiny sacs located at the end of the bronchioles in the lungs.
Larynx Function
- The larynx, or voice box, serves as a passageway for air and is responsible for producing sound during speech.
Trachea Support
- The trachea is held open by C-shaped rings of cartilage, allowing air to pass through.
Air Entry Point
- Air first enters the respiratory system through the mouth or nose, passing through the pharynx (throat) before entering the larynx.
