Ileal Vessels[edit]

The ileal vessels are a group of blood vessels that supply the ileum, which is the final and longest segment of the small intestine. These vessels are primarily branches of the superior mesenteric artery and the superior mesenteric vein.

Arterial Supply[edit]

The arterial supply to the ileum is primarily provided by the ileal branches of the superior mesenteric artery. The superior mesenteric artery arises from the anterior surface of the abdominal aorta just below the level of the celiac trunk.

Superior Mesenteric Artery: This artery gives off numerous branches that supply the small intestine, including the jejunum and ileum. The ileal branches are numerous and form an extensive network of anastomoses, ensuring a rich blood supply to the ileum.

Venous Drainage[edit]

The venous drainage of the ileum is through the ileal veins, which accompany the arteries and drain into the superior mesenteric vein.

Superior Mesenteric Vein: This vein collects blood from the small intestine, including the ileum, and drains into the portal vein, which then carries blood to the liver for processing.

Lymphatic Drainage[edit]

The lymphatic drainage of the ileum follows the arterial supply. Lymph from the ileum drains into the mesenteric lymph nodes, which are located along the superior mesenteric artery.

Nerve Supply[edit]

The nerve supply to the ileum is derived from the autonomic nervous system, including both sympathetic and parasympathetic fibers.

Sympathetic Innervation: Provided by the superior mesenteric plexus, which decreases intestinal motility and secretion.
Parasympathetic Innervation: Provided by the vagus nerve, which increases intestinal motility and secretion.

-'''Ileal vessels''' are a group of [[blood vessels]] that supply the [[ileum]], the third and longest part of the [[small intestine]]. They are part of the [[mesenteric circulation]], which is responsible for supplying the [[digestive system]] with blood.

-==Etymology==
+==Ileal Vessels==
-The term "ileal" is derived from the Latin word "ileum", which means "groin" or "flank". This is likely due to the location of the ileum in the lower part of the abdomen. The term "vessels" is derived from the Latin word "vas", which means "container" or "duct".
-==Anatomy==
+The '''ileal vessels''' are a group of blood vessels that supply the ileum, which is the final and longest segment of the small intestine. These vessels are primarily branches of the [[superior mesenteric artery]] and the [[superior mesenteric vein]].
-The ileal vessels consist of the ileal arteries and the ileal veins. The ileal arteries are branches of the [[superior mesenteric artery]], while the ileal veins drain into the [[superior mesenteric vein]]. These vessels run in the [[mesentery]] of the ileum, a fold of the [[peritoneum]] that attaches the small intestine to the posterior wall of the abdomen.
-==Function==
+[[File:Gray1069.png|thumb|right|300px|Diagram of the superior mesenteric artery and its branches, including the ileal arteries.]]
-The primary function of the ileal vessels is to supply the ileum with oxygenated blood and nutrients, and to remove waste products. The ileum is responsible for the absorption of [[vitamin B12]], [[bile salts]], and any remaining nutrients not absorbed by the [[jejunum]].
-==Clinical significance==
+===Arterial Supply===
-Diseases or conditions that affect the ileal vessels can lead to serious health problems. For example, [[ischemia]] of the ileum can occur if the blood supply to the ileum is reduced or blocked, leading to tissue damage or death. This can be caused by conditions such as [[atherosclerosis]], [[thrombosis]], or [[embolism]].
