During chloride shift or Hamburger phenomenon, when the whole blood is saturated with CO2, following changes occurs. Which one of them is not correct?
Bicarbonate content of plasma and corpuscles increase
Chloride content of plasma diminished and that of the cell is increased
Total base of blood remain unchanged
Water content and volume of corpuscles decrease
D.
Water content and volume of corpuscles decrease
According to Hamburger phenomenon, when the whole blood is saturated with carbon dioxide, the following changes are seen
(i) The bicarbonate contents of plasma and corpuscles increase.
(ii) The chloride content of plasma lo diminished and that of the cell is increased.
(iii) The total base (cations) of both plasma and corpuscles remain unchanged.
(iv) The water content and the volume of corpuscles increase.
(V) When the carbon dioxide is removed from the blood reverse changes takes place.
(vi) When CO2, enters the blood, Cl- from plasma enters RBCs leaving Na+ behind. When CO2 escapes from blood Cl- leaves the cell and combines with Na+ again. Due to this alternate movement of Cl ions, this phenomenon is called chloride shift.
