STUDY GUIDE EXAM 3: BIO202,
2025/2026 WITH CORRECT/ACCURATE
ANSWERS
What are the functions of the respiratory system? - CORRECT
ANSWERS- O2 and CO2 exchange (gas exchange)
speech
smell
affects pH
affects blood pressure
flow of lymph and venous blood
expel abdominal contents
respiratory acidosis - CORRECT ANSWERS- CO2 accumulates
(doesn't exhale enough CO2) caused by hypoventilation (increase
in CO2)
respiratory alkalosis - CORRECT ANSWERS- CO2 elimimated
faster than produced, caused by hyperventilation
what is the difference between the respiratory and the conducting
division? - CORRECT ANSWERS- respiratory consists of alveoli and
other gas exchange regions
,conducting
-passages that serve only for airflow
-no gas exchange
-nostrils through the major bronchioles
what happens to pH and CO2 during hyperventilation and
hypoventilation? - CORRECT ANSWERS- hyper: increases pH and
decreases CO2
hypo: increases CO2 and decreaes pH
metabolic acidosis - CORRECT ANSWERS- increased production of
organic acids such a lactic acid
ingestion of acidic drugs
metabolic alkalosis - CORRECT ANSWERS- rare
oversure of bicarbonates and lots of stomach acid
which system compensates for pH imbalances of respriatory
origin and metabolic origin? - CORRECT ANSWERS- the kidneys
correct imbalances for respiratory origin
the respiratory system corrects for metabolic orgin
when would you use normal saline? - CORRECT ANSWERS-
excessive blood loss
, when would you use Ringer's lactate? - CORRECT ANSWERS- to
treat acidosis
when would you use potassium chloride? - CORRECT ANSWERS-
to treat alkalosis
when would you use 5% dextrose? - CORRECT ANSWERS- to
patients who cannot eat
what organs make up the upper and lower respiratory tract? -
CORRECT ANSWERS- upper: nose, nasal cavity, pharynx, larynx
lower: trachea, bronchi, lungs
What are the functions of the nose? - CORRECT ANSWERS-
warms, cleanses, and humidifies inhaled air
detects odors in the airstream
what is the function of the nasal concha in the nasal cavity -
CORRECT ANSWERS- cleans, warms, and moistens the air
function of olfactory epithelium in nasal cavity - CORRECT
ANSWERS- detects odors
function of respiratory epithelium in nasal cavity - CORRECT
ANSWERS- secretes mucous to trap pathogens
