filter air from foreign organelles or molecules

brings air into body

what is the function of nasal cavity?

filter air

what is the function of nasal vestibule?

filter air

keeps inner nasal moist and warm

what is the function of nasal septum?

divides the nasal cavity

supports and structure nose

nose air flow regulation

what is the function of the nasal cavity(conchae and meatuse)?

have cilia and mucus to capture dust and other molecules

what is the function of posterior nasal apertures?

drains mucus

filter air

acts as an air passageway

what is the function of nasopharynx?

traps dust from entering body

air passageway posterior to nasal cavity

what is the function of oropharynx?

passageway for food and air from left palate

what is the function of laryngopharynx?

passageway for food and air leading to the larynx and esophagus

what is the function of pharyngotympanic tube?

equalizes pressure in the middle ear

drains fluids and mucus from the middle ear to the nasopharynx

what is the function of paranasal sinuses?

lightens up the skull

keeps mucosa lining warm and moists

what is the function of thyroid cartilage?

provides support and protection for the larynx, also called the Adam's apple.

what is the function of cricoid cartilage?

adds structure to larynx to protect airway

what is the function of arytenoid cartilage?

controls movement of vocal cords

helps in sound production

what is the function of corniculate cartilage?

structure support

helps with vocals

what is the function of cuneiform cartilage?

adds structure to the lower respiratory

what is the function of epiglottis?

covers the opening of larynx during swallowing

prevents food from entering the trachea

what is the function of vocal fold?

open and close to produce sound, protecting the airway during swallowing.

what is the function of vestibular fold?

closes glottis during swallowing, known as the false vocal cord

what is the function of glottis?

opening that allows gas comes in or out

prevents food from entering

what position are the true vocal cord found? (inferior or superior)

inferior

what connects the larynx to the main bronchi?

trachea

what includes terminal and respiratory as subtypes?

bronchiole

what is the food passageway posterior to the trachea?

esophagus

what covers the glottis during swallowing of food?

epiglottis

what contains the vocal cords

larynx

what is the nerve that activates the diaphragm during inspiration?

phrenic nerve

what pleural layer lining the walls of the thorax?

parietal pleura

what is the site from which oxygen enters the pulmonary blood?

alveolus

what connects the middle ear to the nasopharynx?

pharyngotympanic tube

what contains opening between the vocal folds?

glottis

what increases air turbulence in nasal cavity?

conchae

what separates the oral cavity from the nasal cavity?

palate

what parts of the respiratory system are included to the anatomical dead space?

trachea and bronchi

what is a dead space?

A volume in the respiratory system where air does not participate in gas exchange, including the trachea, bronchi, and parts of the lungs.
