Respiratory System Flashcards
What our the functions of the Respiratory System?
-Provides an area for gas exchange between the blood and air.
-Carbon dioxide into the lungs, oxygen into blood.
-Prepare air for the lungs by warming, moistening, and filtering it.
-Produces sounds as air passes through the vocal folds.
Aids the sense of smell.

The ______ columnar epithelium propels the ______ towards the _______, where it is swallowed.
The ciliated columnar epithelium propels the mucous towards the pharynx, where it is swallowed.
The ____ cavity and ____ cavity are separated by the bony _____ palate and the ____ palate, made of ________.

The nasal cavity contains _________?
The nasal cavity contains sinuses
The nasal cavity contains sinuses in that :
-Lighten the skull
-Act as resonance chambers for speech
-Produce mucus
-Sinusitis causes swelling and blockage of drainage into the nasal cavities.
Nasal _______ are curled _____ shelves in the nasal _____ that force air flow over the largest surface area of ____ possible.
Nasal conchae are curled bone shelves in the nasal cavity that force air flow over the largest surface area of cilia possible.
Air exits the nasal _____ through the _________.
Air exits the nasal cavity through the nasopharynx.
How does the Pathway of breathing nasal cavity to lungs work?
- Air first enters the nasal and oral cavity, then the pharynx.
- The pharynx is divided into:
- Nasopharynx: Behind the nasal cavity.
- Oropharynx: Behind the oral cavity.
- Laryngopharynx: Above the trachea.
Where do the nasal cavities open above the soft palate?
Where the nasal cavities open above the soft palate
A.) Uvula, soft palate
B.) Eustachian (Auditory) tubes
C.) Pharyngeal tonsils (adenoids)
D.) PSCC
What are the respiratory structures of the pharynx?
1.) Nasopharynx
2.) Oropharynx
A.) Fauces (faucial pillars/arch)
B.) Palatine tonsils - near soft palate
C.) Lingual tonsils - at the back of the tongue.
D.) Stratified squamous/skeletal muscle
How does the Larynx work?
Air must then flow past the epiglottis, a flap of elastic cartilage that routes food to the esophagus and air to the trachea.
Epiglottis
A flap of elastic cartilage that routes food to the esophagus and air to the trachea.
What does the larynx close off during swallowing?
Closes off the trachea during swallowing.
Directly below the epiglottis is the…….
Directly below the epiglottis is the larynx
______________ are cameras placed into the ______ to observe the ______.
Laryngoscopes are cameras placed into the pharynx to observe the epiglottis.
The larynx contains the _____ cords, which _______ to produce sound.

The vocal ____ are located directly posterior to the ______ cartilage, which is externally described as the “______ _______.”
The vocal folds are located directly posterior to the thyroid cartilage, which is externally described as the “Adam’s apple.”
The ______ cartilage covers the area where the ______ joins with the ______ and provides posterior support to the ______.
The cricoid cartilage covers the area where the larynx joins with the trachea and provides posterior support to the larynx.
______ and ______ protect _____ and entrance to the _______
Thyroid and cricoid protect glottis and entrance to the trachea
The trachea Connects with?

Lined with 15-20 C-shaped tracheal cartilages that stiffen the walls of the trachea and prevent it from closing.
The trachea is Lined with ______________ ciliated columnar epithelium.
Lined with pseudostratified ciliated columnar epithelium.
_____ continuously beats in the opposite direction of ________ _____.
Cilia continuously beats in the opposite direction of incoming air
The trachea Moves _____ away from the ______ and out of the _________ tract.
Moves mucus away from the lungs and out of the respiratory tract.
Bronchi deliver air into the ______.
