Alkaline tide

Alkaline tide

Alkaline tide refers to a condition, normally encountered after eating a meal, when stomach acid is released into the stomach causing a temporary increase in pH of the blood.

During HCl excretion in the stomach, the gastric parietal cells extract Cl- anions, CO2, H2O and Na+ cations from the blood plasma and in turn release bicarbonate back into the plasma after the HCl acid is formed from CO2 and H2O constituents. This is to maintain the plasma's electrical balance, as the Cl anions have been extracted. The bicarbonate content causes the venous blood leaving the stomach to be more alkaline than the arterial blood delivered to it.
