Anatomic characteristics of the spleen include:
The aerial supply to the spleen is derived from the splenic aery, which arises within the hepatic aery as the terminal branches of the celiac trunk. The spleen is located with in the dorsal mesentery of the stomach protruding in pa into the omental bursa. The blood vessels enter the spleen in the splenic pedicle, the mesenteric attachment to the wall of the omental bursa, which contains the blood vessels to the spleen. The splenic aery, after it divides into two terminal branches, gives rise to the sho gastric aeries and the left gastroepiploic aery. Ref: Moon D.A., Foreman K.B., Albeine K.H. (2011). Chapter 9.
