major functions of the respiratory system - Answer - supply body with O2 for cellular
respiration
- dispose of CO2, a waste prod of cellular respiration
respiratory and circulatory system - Answer closely coupled
what else does the respiratory function in - Answer olfaction (smell) and speech
how many processes involved in respiration - Answer 4
respiratory system processes - Answer pulmonary ventilation (breathing)
external respiration
pulmonary ventilation - Answer movement of air into and out of the lungs
external respiration - Answer exchange of O2 and CO2 between lungs and blood
circulatory system processes - Answer transport
internal respiration
transport of respiratory gasses - Answer of O2 and CO2 in blood
internal respiration - Answer exchange of O2 and CO2 between systemic blood vessels and
tissues
major organs of upper respiratory - Answer - nose and nasal cavity
- paranasal sinuses
- pharynx
major organs of lower respiratory - Answer - larynx
- trachea
,- bronchi and branches
- lungs and alveoli
nose - Answer external portion supported by bone and cartilage
produces mucus, warms air, resonance chamber
paranasal sinuses - Answer mucosa-lined, air filled cavities in cranial bones
lighten skull, warm air
pharynx - Answer connects nasal cavity to larynx and oral cavity to esophagus
passage way for air and food
larynx - Answer connects pharynx to trachea, houses vocal cords
air passage way
trachea - Answer from larynx and divides into two bronchi
cleans and warms air
bronchial tree - Answer left and right
connects trachea and alveoli
warms air
alveoli - Answer microscopic chambers at terminal of bronchial tree
main site of gas exchange
lungs - Answer composed of alveoli and resp passageways (elastic CT)
lower respiratory system - Answer larynx, trachea, bronchi, lungs
how many zones of lower respiratory system - Answer 2
two zones of lower respiratory system - Answer respiratory zone
conducting zone
respiratory zone - Answer site of gas exchange
, consists or microscopic structures such as respiratory bronchioles, alveolar ducts, and alveoli
conducting zone - Answer conduits that transport gas to and from has exchange sites
includes all other respiratory systems
cleanses, warms, and humidifies air
what is the larynx also referred to as - Answer the voice box
where is the larynx - Answer extends from 3rd to 6th cervical vertebra and attaches to hyoid
bone
opens to laryngopharynx and is continuous with the trachea
3 functions of the larynx - Answer 1. provides patent airway (ability to breath, proper flow)
2. routes air and food into proper channels
3. voice productions (houses vocal folds)
vocal ligaments - Answer forms core of vocal folds (true vocal cords)
vocal cords - Answer contain elastic fibers that appear white because of lack of blood vessels
folds vibrate to produce sound as air rushes up from lungs
glottis - Answer openning between vocal folds
vestibular folds (fasle vocal cords) - Answer superior to vocal folds
no part in sound production
help to close glottis during swallowing
where is the trachea located (windpipe) - Answer extends from larynx into mediastinum,
where it divides into two main bronchi
trachea size - Answer about 4 inches long, 3/4 inch in diameter and very flexible
how many layers in trachea wall - Answer 3
trachea wall layers - Answer 1. mucosa
