{{SI}}
The [[hindgut]] (or '''epigaster''') is the [[posterior]] ([[caudal]]) part of the [[alimentary canal]]. It includes the distal third of the [[transverse colon]] and the [[splenic flexure]], the [[descending colon]], [[sigmoid colon]], [[rectum]] and upper part of the [[anal canal]].
==Blood flow==
Arterial supply is by the [[Inferior mesenteric artery]], and venous drainage is to the [[portal venous system]]. Lymphatic drainage is to the [[chyle cistern]].

==Autonomic innervation==
The hindgut is innervated via the [[inferior mesenteric plexus]]. Sympathetic innervation is from the [[Lumbar splanchnic nerves]] (L1-L2), parasympathetic innervation is from S2-S4.
