title: [Functional anatomy of stomach circulation: localizing factors in the pathogenesis of stomach ulcer].
abstract: Comparative vertebrate anatomy shows that acid secretion and wall stress processes typically occur in different compartments. In the human single-chamber stomach both processes are physiologically separated in time. If both processes take place in one hollow organ at the same time, focal ischemia will occur. Using the microsphere technique a submucous steal-phenomenon, which the effect is due to, has been reproduced experimentally. A network model of the human gastric vascular bed produces borderline infarcts at the preferred sites of human gastric ulcer.
