Study Notes
Respiratory System Overview
- Controls breathing, delivering oxygen to the blood, and removing carbon dioxide.
- Breathing involves inhalation and exhalation.
Inhalation
- Diaphragm flattens.
- Creates a vacuum in the chest cavity.
- Lungs expand.
Exhalation
- Diaphragm relaxes and becomes dome-shaped.
- Decreases the volume of the lungs.
- Pushes air out.
Trachea Structure
- Supported by bands of cartilage to prevent collapse.
Alveoli Function
- Tiny, grape-like clusters at the end of the bronchioles.
- Extremely small size maximizes surface area.
- Increases the rate of gas exchange (diffusion).
