What is the arterial vascularization of the stomach?
I - The abundant arterial vascularization of the stomach originates in the celiac trunk and its branches.
II - Most of the irrigation comes from anastomoses formed along the lesser curvature by the right and left gastric arteries, and along the greater curvature by the right and left gastroepiploic (gastroomental) arteries.
III - The fundus and the pyloric portion of the stomach are not irrigated by the same arteries.
IV - The arterial vascularization of the stomach is not relevant for the digestive process.
a) I and II are correct.
b) II and III are correct.
c) I and IV are correct.
d) I, II, and III are correct.

A alternativa correta é a letra "a) I e II estão corretas". A vascularização arterial abundante do estômago origina-se no tronco celíaco e seus ramos. A maior parte da irrigação vem das anastomoses formadas ao longo da curvatura menor pelas artérias gástricas direita e esquerda e ao longo da curvatura maior pelas artérias gastroepiploicas (gastroomentais) direita e esquerda. A afirmação III está incorreta, pois a porção pilórica do estômago é irrigada pela artéria pilórica. A afirmação IV também está incorreta, pois a vascularização arterial é essencial para o processo digestivo.
