What is the primary function of the respiratory system?
Provides oxygen for cellular metabolism and removes carbon dioxide
The respiratory system is essential for gas exchange in the body.
What are the secondary functions of the respiratory system?
- Sense of smell
- Voice production
- Maintains acid-base balance
These functions highlight the respiratory system’s additional roles beyond gas exchange.
What does the upper airway function in the respiratory system include?
- Filters
- Humidifies
- Warms air
The upper airway plays a crucial role in preparing air for the lungs.
What is the structure of the nose in the respiratory system?
Lining of ciliated mucosa divided by a septum into right and left sides with olfactory receptors
The nose is key for filtering and sensing smells.
What are the paranasal sinuses?
- Frontal Sinus (biggest)
- Ethmoid Sinus
- Maxillary Sinus (widest)
- Sphenoid Sinus
These sinuses help in humidifying and warming the air.
What is sinusitis and what is its common cause?
Sinusitis is often caused by a viral infection that is self-limiting
Medications are used primarily for symptom control.
What is the best management for sinusitis?
Proper hydration
Staying hydrated can help alleviate symptoms of sinusitis.
What structures does the pharynx connect?
Nasal cavity, oral cavity, and larynx
The pharynx serves as a passageway for air and food.
What are the functions of the tonsils?
Lymphatic function and immunity
Tonsils play a role in protecting against infections.
What are the three parts of the pharynx?
- Nasopharynx - air
- Oropharynx - air and food
- Laryngopharynx - air
Each part of the pharynx has specific roles in respiration and digestion.
Fill in the blank: The nasal passage is a part of the _____ which leads to the oral cavity and larynx.
pharynx
The pharynx functions as a shared pathway for air and food.
What procedures may involve the laryngopharynx?
- Intubation
- Bronchoscopy
These procedures are critical in managing airway and respiratory issues.
What is the larynx commonly known as?
Voicebox
What is the terminal part of the upper airway?
Larynx
What is the primary function of the larynx?
Produces voice
What is the thyroid cartilage also known as?
Adams apple
What type of cartilage is the cricoid cartilage?
Signet ring cartilage
What is the function of the epiglottis?
Lid/flap
What condition is indicated by the term epiglottitis?
DON’T insert anything and DON’T examine
What specific structure in the larynx produces the voice?
Vocal cords
What is the mechanism that produces voice?
Vibration
During what phase does voice production occur?
Expiration
What is the primary function of the lower airway?
Enables gas exchange
The lower airway is crucial for the process of respiration.
What is another name for the trachea?
Windpipe
The trachea is also known as the windpipe.
