what happens to co2 transport in pulmonary capillary regarding chloride shift???

1.there will be no change ..

2.cl ions move out of the RBC's

3.cl ions moves into the RBC's.

hey where you been mice to see you !

oh yeah the question

3.

sorry NICE to see you

respiratory physiology

hi guys ,this means you people haven't gone properly through kaplan dvd's...


  #6

In pulmonary cappilaries, HCO3- goes into RBC in order to combine with H+ and thanks to carboanhidrase converts to CO2 which is then exhaled. In order electrical equilibrium not to be disturbed, chloride ions leave RBC. The opposite occurs in tissues. So, the answer would be B not C. C is in tissues.

Ohh yeah u are right....

I did not read the Q properly thanks for correcting...




  #8

Yes C occurs in systemic capillaries (Cl ions move into RBC'S in order to equilibriate with HCO3- ions ) and the reverse occurs in pulmonary capillary....so B is correct...
