In addition to transporting oxygen red cells also remove C02
in the form of [HCO3]-, from actively metabolizing
cells. As erythrocytes circulate through tissue capillaries, [HCO3]-
is picked up and cytoplasmic Cl- is lost. The reverse processes
- [HCO3]- efflux and Cl- uptake - occur
in the small capillaries of the lungs where the concentration of C02
is naturally quite low. Consider the membrane mechanism(s) possibly responsible
for these transport phenomena and answer the following questions. |
