Respiratory System
Superior, middle, and inferior nasal conchae
create turbulence in the air to trap particulate matter in mucus
The respiratory mucosa consists of
epithelium and underlying layer of areolar tissue
The nasal cavity is separated from the oral cavity by the
hard plalate
Inhaling through the nostrils is preferred over the mouth because
it allows better conditioning of the inhaled air.
The ________ is shared by the respiratory and digestive systems.
pharynx
During a choking episode, most foreign objects are lodged in the ________ bronchus due to its larger diameter and steeper angle.
right primary
the opening to the larynx.
the Glottis
The elastic cartilage that covers the opening to the larynx during swallowing is the
Epiglottis
The auditory tubes open into the
Nasopharynx (top)
The portion of the pharynx that receives both air and food is the. Palatine tonsils line the walls of. is lined by stratified squamous epithelium.
Oropharynx (mouth, middle)
Air passing through the glottis vibrates the vocal folds and produces. Sound production at the Larynx.
Phonation
A pair of ligaments covered by laryngeal epithelium that function in sound production are the
vocal folds
Largest Cartilage of the Larynx. ligaments connect to the Cricoid cartilage and is a good cite for tracheostomy.
Thyroid
The larynx contains 9 cartilages
Thyroid, Hyaline, Cricoid, Elastic (epiglottis), Arytenoid, Corniculate, Cuneiform
The larynx, trachea, bronchi, and bronchioles all make up the
lower respiratory tract.
Tension on the vocal cords is regulated by the
movement of the arytenoid cartilages and contraction of laryngeal muscles.
The nasal cavity opens into the nasopharynx through a connection known as the
Internal Nares
The vocal folds are located within the
Larynx
The respiratory defense system is important because it
keeps out debris. helps filter the air. keeps out pathogens. helps warm the air.
The respiratory epithelium of the conducting airways consists of
pseudostratified ciliated columnar epithelium.
