The Spleen is located in the abdomen, it accomplishes several functions as lymphoid cells generation, hemoglobin and iron metabolism, etc. It is deeply affected in abdominal injuries, that could lead to splenectomies. In this order it is vital an appropriate knowledge of the blood supply to this organ. In these way 51 splenic arteries belonging to Venezuelan human fetuses were observed; the gestational ages were from 20 to 40 weeks, they were previously 10 % paraformaldehyde fixed, and afterwards they were red vinyl perfused. After a careful observation of the sample we found: In 78.43 splenic artery gives off 2 terminal braches (superior and inferior), in 21.57 % the artery gives origin to three terminal branches (superior, intermediate and inferior). Polaris superior artery was present in 33.33 % of the sample. Gastroepiploic artery was seen arising from inferior splenic branch in 82.35 % of the sample, and in 5.88 % taking origin from superior splenic branch, also it was present in 72.55 % of the serie.
