| part of respiratory system that consists only of the passages that serve airflow |
|
|
Term
|
Definition
1. ventilation of lungs 2. exchange of gases between air and blood and between blood and tissue fluid 3. use of oxygen in cellular metabolism |
|
|
Term

|
|
Term
|
Definition
| airway from nose to larynx (head and neck) |
|
|

|
|
Term
|
Definition
- cleanses inhaled air - detects odor -resonating chamber that amplifies voice |
|

|
|
Term
|
Definition
| divides nasal cavity into right and left chambers called nasal fossae |
|
|
Term
|

| separates nasal cavity from oral cavity and allows you to breathe with food in your mouth |
|
|
Term

|
|
Term
|
Definition
| muscular funnel extending from choanae to larynx |
|
|
Term
|
Definition
posterior to choanae and dorsal to soft palate - receives auditory tubes from middle ear and houses pharyngeal tonsil -only passes air |
|
|
Term
|
Definition
between soft palate and roof of tongue - contains palatine and lingual tonsils - -passes air, food and drink |
|
|
Term
|
Definition
| opening of oral cavity into the pharynx |
|
|
Term
|
Definition
begins with union of nasopharyns and oropharynx - esophagus begins here -passes air, food and drink |
|
|
Term
|
Definition
voicebox; cartilage chamber that keeps food and drink out of airway and also produces sound
-during swallowing, muscles move larynx upward while tongue moves epiglottis downward to meet it so epiglottis directs food into esophageal dorsal to airway |
|
|
Term
|
Definition
| opening of larynx and is guarded by flap of tissue called epiglottis |
|
|
Term
|
Definition
-located relatively high and allows them to breathe while swallowing -by age 2, muscle of tongue pushes it lower |
|
|
Term
|
Definition
most superior muscle in larynx, supportive plate in epiglottis |
|
|
Term
|
Definition
| largest muscle in larynx, top part is "adam's apple" or laryngeal prominence. testosterone stimulates growth of prominence |
|
|
Term
|
Definition
| muscle in larynx that connects larynx to trachea |
|
|
Term
|
Definition
pair of muscles in larynx, posterior to thyroid - function in speech |
|
|
Term
|
Definition
pair of muscles in larynx that attach to arytenoid - function in speech |
|
|
Term
|
Definition
| pair of muscles in larynx |
|
|
Term
| Intrinsic muscles of larynx |
|
Definition
operate vocal cords by pulling on corniculate and arytenoid cartilages - sounds formed into words by pharynx, oral cavity,tongue and lips |
|
|
Term
| extrinsic muscles of larynx |
|
Definition
| connect larynx to hyoid bone and elevates larynx during swallowing |
|
|
Term
| vestibular folds of larynx |
|
Definition
| closes glottis during swallowing |
|
|
Term
| vocal cords (vocal folds) of larynx |
|
Definition
| produce sound when air passes between them |
|
|
Term
|
Definition
-"windpipe" anterior to esophagus -supported by C rings of hyaline cartilage that keeps it from collapsing when you inhale - at inferior end, branches into right and left primary bronchi which supply the lungs |
|
|
Term
|
Definition
| smooth muscle in gap of C rings that contracts to adjust tracheal airflow |
