Study Notes
Respiratory System Components and Functions
- The pharyngeal tonsil plays a role in the respiratory system by helping to filter out pathogens and other debris from inhaled air.
- The epiglottis prevents swallowed food and drink from entering the respiratory tract by separating the trachea from the esophagus.
Voice Production
- Voice production in humans is made possible by the vocal folds (vocal cords) in the larynx.
Trachea Function
- The trachea, or windpipe, connects the throat to the lungs and serves as a passageway for air to enter the lungs.
Uvula Function
- The uvula, a small, soft piece of tissue hanging from the back of the throat, helps to produce sounds and modulate speech.
Vocal Fold Inflammation
- Inflammation of the vocal folds can cause laryngitis.
Larynx Components
- The thyroid cartilage is the largest piece of cartilage in the larynx.
Pharyngeal Region
- The pharynx, extending from the epiglottis to the esophagus, is a common pathway for both food and air.
Nasal Cavity Function
- The main function of the nasal cavity in the respiratory system is to warm, humidify, and filter the air we breathe.
