|
respiratory surfaces are
|
thin and have large areas (maximize gas exchange)
|
|
|
cellular respiration
|
most efficient catabolic pathway for the production of ATP in which oxygen is consumed
|
|
|
outerskin (worms)
|
moist skin allows for exchange of gaes by diffusion
|
|
|
gills
|
surgaces area of gill > surface area of body
|
|
|
countercurrent exchange
|
opp. direction of flowing between blood and oxygen
|
|
|
ventilation
|
increase flow of respiration medium over resp. surface
|
|
|
tracheal system (insects)
|
air tubes branch throughout body
|
|
|
trachea is the
|
largest tubes-open to outside
diffusion thru this brings in ozygen and removes CO2 to suppost cellular respiration |
|
|
lungs
|
ciculatory systems traponsorts gases between lungs and body and has a moist surface
|
|
|
lung size and complexity
|
correlated with animals metabolic rate
|
|
|
pisitive pressure breathing
|
pushing air into lungs
|
|
|
neg. pressure breathing (humans)
|
pulling air into the lungs
|
|
|
breathing
|
enter thru nostrils and flows thru nasal cavity
|
|
|
larynx
|
epiglottis covers windpipi wen food is swallowed
|
|
|
trachea brachnes
|
branches into two bronchi tubes-each to each lunch
|
|
|
bronchiolies end in
|
end in alveolis( cluster of air sacs)
|
|
|
bronchus is
|
inside the lunds, branching into bronchiloies (finer tubes)
|
|
|
steps of breathing
|
inhale thru nostil and thru nasal cavity-thru pharnyx and larynx-thru windpipe- air into each bronchi tube- then to brinchiolis and then into aveoli-
|
|
|
capillaries
|
small blood vessels with thin walls
|
|
|
capillaries have thin wals because
|
air easily seeps thru into bloodstream
|
|
|
diaphragm
|
muscle that controls the breathing process
relaxes-air in lungs and chest collapses |
