[Blood flow as a protective mechanism of the stomach and duodenum].
Blood flow in the stomach and duodenum is not only important for the transport of O2, CO2 and substrates, but also a protective mechanism against luminal H+. Back diffusion of H+ stimulates blood flow in the stomach, thus preventing mucosal acidosis by removing H+. Another important function of blood flow is the transport of HCO3- for extra and intracellular buffering of H+.
