The duodenum recieves blood from the '''coeliac artery''' and the '''cranial mesenteric artery'''. Both are branches of the aorta. The '''cranial mesenteric vein''' drains blood from the duodenum into the '''portal vein'''. This blood, carrying the products of digestion, enters the [[Liver - Anatomy & Physiology|liver]].

The mesoduodenum is relatively short, so the duodenum is closely tethered in a constant position. The descending duodenum is attached to the base of the [[Caecum - Anatomy & Physiology|caecum]]. The descending duodenum runs caudally beneath the [[Liver - Anatomy & Physiology|liver]] to the caudal pole of the right [[Urinary System Overview - Anatomy & Physiology|kidney]] where it has it's caudal flexure to become the ascending duodenum.

The mesoduodenum is relatively short. The first part of the descending duodenum rises almost vertically within the ribcage, in close apposition to the [[Liver - Anatomy & Physiology|liver]]. It turns level with the tuber coxae. The first part of the duodenum is attached to the [[Liver - Anatomy & Physiology|liver]] by the lesser omentum. The descending duodenum also provides attachment for the superficial and deep sheets of the greater omentum.
