Ventilation
Ventilation
The process of moving air into and out of the lungs, allowing for gas exchange.
Alveoli
Alveoli
Tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged between the air and the blood.
Trachea

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.
