Lab Quiz #5 procedures and histology Flashcards
normally when blood carbon dioxide levels increase does the rate of respiration increase or decrease?
increase
goblet cells
bronchiole
an increase in carbon dioxide will be followed by an increase or decrease in rate of depth?
increase
was the subject able to hold their breath longer when they did or didn’t hyperventilate first (without bag)?
when they did hyperventilate first
followed by the decrease in blood carbon dioxide levels is followed by an increase or decrease in rate of depth ?
decrease
can residual volume be measured?
no
what is the tidal volume?
volume of air moved in or out of the lungs in a quiet breath (in OR out)
what is the normal range for ERV?
about 1000mL in males and 700mL in females
hyaline cartilage of trachea
after hyperventilating in fresh air, blood carbon dioxide increases or decreases?
decreases
diaphram (striations)
Alveoli
what equipment do you nee for the human respiratory volume test?
1) nose clip 2) mouthpiece 3) filter 4) spirometry pad 5) flow head
what is residual volume (RV)?
amount of air left in lungs after forceful exhalation
what is the normal range for RV?
1200mL in males and 1100mL in females
what is the inspiratory reserve volume (IRV)?
normal inhale followed by forceful inhale
what is the normal range for tidal volume (TV)
400-500mL
what is the trachea lined with?
pseudostratified columnar epithelium
what is vital capacity (VC)?
forceful inhale followed by forceful exhale
what is the normal range for IRV?
3000 mL in males and 1900 mL in females
hyperventilation into the paper bag causes the blood carbon dioxide content to decrease or increase?
increase
what is the formula for IRV?
VC= TV + ERV + IRV which rearranges to IRV=VC (TV + ERV)
