GH 125 Unit 6 Exam With
Complete Solution
Function of upper respiratory tract - ANSWER clean, warm, and humidify air
Where is the eustachian tube located? - ANSWER middle ear
What does the Eustachian tube connect? - ANSWER middle ear to
nasopharynx
What do we force air thru when we speak? - ANSWER Vocal folds
What opening is closed off by the epiglottis? When? - ANSWER Larynx when
swallowing
function of lower respiratory tract - ANSWER Cleanse, warm humidify air,
and exchange gases
What helps hold the lower respiratory tract open? - ANSWER Cartilage rings
of trachea
What is the parietal pleura? - ANSWER lines the walls of the thoracic cavity
What is the visceral pleura? - ANSWER serous membrane that covers lungs
What happens if the pleura system is compromised with a break or blood in
the space. - ANSWER
Where does pulmonary gas exchange occur? - ANSWER alveoli
Where does systemic gas exchange occur? - ANSWER at the capillary
networks of the tissues
, What is diffusion? - ANSWER Movement of molecules from high to low
concentration
Where does diffusion take place in the respiratory system? - ANSWER alveoli
What are normal respiratory rates? - ANSWER Adult: 12-18 breaths/min
Child: 20-25 breaths/min
What is normal inspired volume? - ANSWER 500 mL
What is the diaphragms position at rest and contracting? - ANSWER When
breathing in contracts and moves downward
Where are the respiratory control centers located? - ANSWER medulla and
pons
Where are chemoreceptors located? - ANSWER carotid and aortic bodies
What cause chemoreceptors to signal for increased breathing? - ANSWER
Decreased blood oxygen, increased blood carbon dioxide, and increased
blood acidity(lower ph)
