Chapter 20 - Respiratory System Flashcards
xrespiratory system
system of tubes that delivers air to and from the lungs
functions of the respiratory system
gas exchange, pH balance, olfaction, communication
effectors of pH balance
urinary system, CO2 in blood
olfaction
sense of smell
how does the respiratory system contribute to communication
speech, vocalization, and the larynx
passage of air through the RS
nose, pharynx, larynx, trachea, bronchi, alveoli
pharynx is also called the
throat
the larynx is also called the
voicebox
trachea is also called
windpipe
functions of the nose
warms, cleanses, humidifies air, olfaction, voice resonation
nasal mucosa
mucosa lining the nasal cavity
types of epithelium in the nose
respiratory and olfactory epithelium
respiratory epithelium
ciliated pseudostratified columnar epithelium
purpose of goblet cells in respiratory epithelium
to produce mucus
purpose of cilia in respiratory epithelium
move mucus toward pharynx for swallowing
olfactory epithelium
sensory cells that lines part of the roof of the nasal cavity and septum
purpose of cilia in olfactory epithelium
immobile to bind to odorants
pharynx
muscular funnel extending from the nasal cavity to larynx
the pharynx is a passage way for
food and air
the larynx is made of
cartilage
larynx location
anterior to esophagus
superior to trachea
larynx function
keeps food and water out of airway
phonation
phonation
sound production
superior vestibular fold
closes the larynx is swallowing
