(Top) Graphic shows the liver is retracted upward and the stomach transected to reveal the pancreas and spleen. The splenic artery and
vein course along the body of the pancreas, and the tail of the pancreas lies within the splenorenal ligament. The gastrosplenic
ligament carries the short gastric and left gastroepiploic vessels to the stomach and spleen. The splenic vein receives the inferior
mesenteric vein and joins the superior mesenteric vein behind the neck of the pancreas to form the portal vein. (Bottom) Histologic
section of a normal spleen viewed at low power shows white pulp and red pulp. A thin splenic capsule with slivers of branching
trabeculae is also noted.
