Superior Mesenteric Artery(SMA) | Course | Divisions | Termination
The superior mesenteric artery (SMA) is a major artery of the abdomen. It arises from the abdominal aorta, and supplies arterial blood to the organs of the midgut – which spans from the major duodenal papilla (of the duodenum) to the proximal 2/3 of the transverse colon.
The superior mesenteric artery is the second of the three major anterior branches of the abdominal aorta (the other two are the coeliac trunk and inferior mesenteric artery). It arises anteriorly from the abdominal aorta at the level of the L1 vertebrae, immediately inferior to the origin of the coeliac trunk.
After arising from the abdominal aorta, the superior mesenteric artery descends down the posterior aspect of the abdomen. At this point, it has several important anatomical relations:

The superior mesenteric artery (SMA) is a major artery of the abdomen. It arises from the abdominal aorta, and supplies arterial blood to the organs of the midgut – which spans from the major duodenal papilla (of the duodenum) to the proximal 2/3 of the transverse colon.
The superior mesenteric artery is the second of the three major anterior branches of the abdominal aorta (the other two are the coeliac trunk and inferior mesenteric artery). It arises anteriorly from the abdominal aorta at the level of the L1 vertebrae, immediately inferior to the origin of the coeliac trunk.
After arising from the abdominal aorta, the superior mesenteric artery descends down the posterior aspect of the abdomen. At this point, it has several important anatomical relations:
Anterior to the SMA – pyloric part of the stomach, splenic vein and neck of the pancreas.
Posterior to the SMA – left renal vein, uncinate process of the pancreas and inferior part of the duodenum.
The uncinate process is the only part of the pancreas that hooks around the back of the SMA.
Major Branches
The superior mesenteric artery then gives rise to various branches that supply the small intestines, cecum, ascending and part of the transverse colon
Inferior Pancreaticoduodenal Artery
The inferior pancreaticoduodenal artery is the first branch of the SMA. It forms anterior and posterior vessels, which anastomose with branches of the superior pancreaticoduodenal artery (derived from the coeliac trunk). This network supplies the inferior region of the head of the pancreas, the uncinate process, and the duodenum.
Jejunal and Ileal Arteries
By TeachMeSeries Ltd (2020)
Fig 1.3 - Arterial supply to the jejunum and ileum of the small intestine
Fig 2 – The characteristic features of the jejunal and ileal blood supply.
The superior mesenteric artery gives rise to numerous arteries that supply the jejunum and ileum.
The arteries pass between the layers of the mesentery and form anastomotic arcades – from which smaller, straight arteries (known as the “vasa recta”) arise to supply the organs (fig 2).
The jejunal blood supply is characterised by a smaller number of arterial arcades, but longer vasa recta. In contrast, the ileal blood supply is marked by more arterial arcades with shorter vasa recta.
Middle and Right Colic Arteries
The right and middle colic arteries arise from the right side of the superior mesenteric artery to supply the colon:
Middle colic artery – supplies the transverse colon.
Right colic artery – supplies the ascending colon.
Ileocolic Artery
The ileocolic artery is the final major branch of the superior mesenteric artery. It passes inferiorly and to the right, giving rise to branches to the ascending colon, appendix, cecum, and ileum. In cases of appendectomy, the appendicular artery is ligated.
Clinical Relevance: Occlusion of the Superior Mesenteric Artery
There are a number of cause of superior mesenteric artery occlusion, including thrombosis, embolism, abdominal aortic aneurysm and aortic dissection.
Often acute, occlusion of the SMA restricts blood flow to the midgut, resulting in intestinal ischaemia. It is more common in the elderly, and most usually presents with abdominal pain. The most useful investigation in this scenario is CT scan of the abdomen.
Treatment is surgical.

Anatomy of Ileum Animation: Blood supply, Venous drainage, Histology, Innervation, Functions
Definition
----------------
The ileum is the third and final part of the small intestine. It follows the duodenum and the jejunum and leads into the cecum, which is the first part of the large intestine. The ileum is typically between 3.5 and 4 meters long and its primary role is to absorb nutrients and salts that were not absorbed by the jejunum.
Blood Supply
---------------------
The ileum receives its blood supply primarily from the ileal branches of the superior mesenteric artery. These are called the straight arteries or arteriae rectae. The blood flows into the small intestine through a series of progressively smaller vessels known as arterial arcades, then finally reaching the straight arteries which supply the gut wall.
After oxygen and nutrients have been extracted from the blood, it is returned to the heart via the superior mesenteric vein. This vein drains directly into the portal vein, which carries the blood to the liver for further metabolism before it is returned to systemic circulation.
Innervation
------------------
The innervation of the ileum involves both the parasympathetic and sympathetic nervous systems. Parasympathetic innervation is mainly provided by the vagus nerve, which helps to stimulate peristalsis and secretory activities. The coeliac and superior mesenteric plexuses mainly provide sympathetic innervation, which generally has inhibitory effects, slowing peristalsis and reducing secretion.
Histology
----------------
The structure of the ileum, like other parts of the gastrointestinal tract, is divided into several layers:
Mucosa: This innermost layer comes into direct contact with digested food (chyme). It's made up of simple columnar epithelium, which has many folds and projections (villi and microvilli) to increase surface area for better nutrient absorption. The ileum is distinctive for its numerous aggregated lymphoid follicles, known as Peyer's patches, which play a significant role in immune response.
Submucosa: This layer is composed of dense connective tissue and contains blood vessels, lymphatic vessels, and nerves that help control the contraction and dilation of the ileum.
Muscularis: The muscularis is made up of two layers of smooth muscle (inner circular and outer longitudinal). These muscle layers contract in a rhythmic manner, propelling the food along the intestine (a process called peristalsis).
Serosa: The outermost layer, the serosa, is a layer of simple squamous epithelium which secretes a fluid to reduce friction with other organs in the abdomen, allowing the ileum to move smoothly during digestion.
Function
--------------
The primary functions of the ileum are the continuation of the digestion process and nutrient absorption, but it also has other specific roles:
Digestion and absorption: The ileum completes the process of enzymatic digestion initiated in the duodenum. It absorbs important nutrients like vitamin B12, bile salts, and any remaining products of digestion including carbohydrates, proteins, and lipids.
Immune function: Peyer's patches in the ileum form an important part of the immune system, protecting the body from harmful bacteria that might enter through the digestive tract.
Bile salts and vitamin B12 absorption: The ileum is also crucial in the reabsorption of bile salts, which are used for the digestion of dietary fats, and vitamin B12, which is essential for the formation of red blood cells and the functioning of the nervous system.
Ileocecal valve: At the junction of the ileum and the large intestine is the ileocecal valve, which prevents the backflow of colonic contents into the ileum.

Anatomy of Ileum Animation: Blood supply, Venous drainage, Histology, Innervation, Functions
Definition
----------------
The ileum is the third and final part of the small intestine. It follows the duodenum and the jejunum and leads into the cecum, which is the first part of the large intestine. The ileum is typically between 3.5 and 4 meters long and its primary role is to absorb nutrients and salts that were not absorbed by the jejunum.
Blood Supply
---------------------
The ileum receives its blood supply primarily from the ileal branches of the superior mesenteric artery. These are called the straight arteries or arteriae rectae. The blood flows into the small intestine through a series of progressively smaller vessels known as arterial arcades, then finally reaching the straight arteries which supply the gut wall.
After oxygen and nutrients have been extracted from the blood, it is returned to the heart via the superior mesenteric vein. This vein drains directly into the portal vein, which carries the blood to the liver for further metabolism before it is returned to systemic circulation.
Innervation
------------------
The innervation of the ileum involves both the parasympathetic and sympathetic nervous systems. Parasympathetic innervation is mainly provided by the vagus nerve, which helps to stimulate peristalsis and secretory activities. The coeliac and superior mesenteric plexuses mainly provide sympathetic innervation, which generally has inhibitory effects, slowing peristalsis and reducing secretion.
Histology
----------------
The structure of the ileum, like other parts of the gastrointestinal tract, is divided into several layers:
Mucosa: This innermost layer comes into direct contact with digested food (chyme). It's made up of simple columnar epithelium, which has many folds and projections (villi and microvilli) to increase surface area for better nutrient absorption. The ileum is distinctive for its numerous aggregated lymphoid follicles, known as Peyer's patches, which play a significant role in immune response.
Submucosa: This layer is composed of dense connective tissue and contains blood vessels, lymphatic vessels, and nerves that help control the contraction and dilation of the ileum.
Muscularis: The muscularis is made up of two layers of smooth muscle (inner circular and outer longitudinal). These muscle layers contract in a rhythmic manner, propelling the food along the intestine (a process called peristalsis).
Serosa: The outermost layer, the serosa, is a layer of simple squamous epithelium which secretes a fluid to reduce friction with other organs in the abdomen, allowing the ileum to move smoothly during digestion.
Function
--------------
The primary functions of the ileum are the continuation of the digestion process and nutrient absorption, but it also has other specific roles:
Digestion and absorption: The ileum completes the process of enzymatic digestion initiated in the duodenum. It absorbs important nutrients like vitamin B12, bile salts, and any remaining products of digestion including carbohydrates, proteins, and lipids.
Immune function: Peyer's patches in the ileum form an important part of the immune system, protecting the body from harmful bacteria that might enter through the digestive tract.
Bile salts and vitamin B12 absorption: The ileum is also crucial in the reabsorption of bile salts, which are used for the digestion of dietary fats, and vitamin B12, which is essential for the formation of red blood cells and the functioning of the nervous system.
Ileocecal valve: At the junction of the ileum and the large intestine is the ileocecal valve, which prevents the backflow of colonic contents into the ileum.
