This structure is found at the left hypochondrium.

Artery

bullet

Splenic artery, which is a branch of the celiac trunk. The splenic artery enters the lienorenal ligament and in the hilum divides into five arterioles, which are said to supply five segments of the spleen, although only 2-3 segments can be identified using corrosion casts methods. The segments  are vascular  and they are concentric so that 2 or more arterioles may supply one concentric segment. Hence in partial splenectomy, tying some vessels, which supply a lobe or segment of the spleen will lead to auto-infarction of that lobe only (usually external concentric lobe) leaving the other lobes (inner ones).

Vein

bullet

Splenic venules come together to form the splenic vein, which forms the portal vein with the superior mesenteric vein, behind the neck of pancreas.

Nerves

bullet

Only sympathetic fibers reach the spleen from the celiac plexus, arising from the thoracic splanchnic nerves.
