external and internal resp

Question 1

what is another name for external respiration?

Answer 1

pulmonary respiration

Question 2

what is another name for internal respiration?

Answer 2

tissue respiration

Question 3

Exchange of O2 and CO2 between air in alveoli and blood in pulmonary capillaries

Answer 3

external respiration

Question 4

function of external respiration

Answer 4

Converts deoxygenated to oxygenated blood, gets rid of CO2 from blood to air

Question 5

when the pO2 is higher in the alveoli than that of deoxygenated blood, what does oxygen do?

Answer 5

it will enter the blood

Question 6

compare the Palv and PO2 of the doexygenated blood when oxygen enters the deoxygenated blood

Answer 6

PO2 of alv > PO2 of the deoxygenated blood

O2 diffuses from alveoli into blood

Palv 104 > P O2 blood 40

Question 7

Compare the pCO2 in the deoxygenated blood to that of the pCO2 of the alveoli

Answer 7

pCO2 deoxygenated blood > pCO2 of alveoli

CO2 diffuses from deoxygenated blood into alveoli

pCO2 deox blood 45 > pCO2 alveoli 40

Question 8

Which is more soluble: CO2 or O2

Answer 8

CO2

this is why the pressure gradient difference doesn’t have to be as large

Question 9

Exchange of O2 and CO2 between blood and tissue they serve

Answer 9

internal respiration

Question 10

what is the function of internal respiration

Answer 10

Oxygenates tissues and removes CO2 produced during aerobic respiration.

Question 11

when pO2 blood > pO2 tissues, what happens?

Answer 11

Oxygen will diffuse into the tissues

pO2 blood 95 > pO2 tissue 40

Question 12

when pCO2 tissues > pCO2 blood, what happens?

Answer 12

CO2 will diffuse into the blood.

pCO2 tissue 45 > pCO2 blood 40
