Study Notes
Respiratory System Components
- The trachea serves as the passageway of air into the lungs.
- The exchange of gases takes place in the alveoli, the tiny air sacs located at the end of the bronchioles in the lungs.
Diaphragm Function
- The diaphragm, a dome-shaped muscle, separates the chest cavity from the abdominal cavity and is responsible for expanding the chest cavity to facilitate inhalation.
Respiratory System Connections
- The bronchi, which branch off from the trachea, connect the trachea to the lungs.
Nose and Nasal Passages
- The nose and nasal passages warm, humidify, and filter the air we breathe, preparing it for the lungs.
- They also contain small hairs called cilia and mucous membranes that help trap dust and other particles, preventing them from entering the lungs.
