Answer: rich, poor
●● during exhalation, O2 ___ and CO2 ___ air are removed from the
lungs
Answer: poor, rich
●● what is exhalation?
Answer: air moving from the lungs to the external environment
●● what is respiration?
,Answer: exchange of gases across a membrane into and out of a blood
vessel
●● during respiration, CO2 diffuses from the capillary blood into the
___ while oxygen diffuses from the lungs into the ___
Answer: lungs, capillary blood
●● what is tissue respiration
Answer: exchange of O2/CO2 between the blood in the systemic
capillaries
●● what is the cellular respiration equation?
Answer: C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
●● what happens to oxygen during external respiration?
Answer: moves from the alveoli across the alveolar membrane into the
pulmonary capillary bed
●● what happens to carbon dioxide during external respiration?
Answer: moves from the capillary bed across the alveolar membrane
into the alveoli
●● what happens to carbon dioxide during internal respiration?
, Answer: moves from the interstitial fluid across the systemic capillary
membrane into the systemic capillary bed
●● what happens to oxygen during internal respiration?
Answer: moves from the systemic capillary bed across the systemic
capillary membrane into the interstitial fluid where it is used to create
ATP
