Ileocolic Vein
The ileocolic vein is a vein which drains the ileum, colon, and cecum The cecum or caecum is a pouch within the peritoneum that is considered to be the beginning of the large intestine. It is typically located on the right side of the body (the same side of the body as the appendix (anatomy), appendix, to which i .... Veins of the torso {{circulatory-stub ...

Portal Vein
The portal vein or hepatic portal vein (HPV) is a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver. This blood contains nutrients and toxins extracted from digested contents. Approximately 75% of total liver blood flow is through the portal vein, with the remainder coming from the hepatic artery proper. The blood leaves the liver to the heart in the hepatic veins. The portal vein is not a true vein, because it conducts blood to capillary beds in the liver and not directly to the heart. It is a major component of the hepatic portal system, one of only two portal venous systems in the body – with the hypophyseal portal system being the other. The portal vein is usually formed by the confluence of the superior mesenteric, splenic veins, inferior mesenteric, left, right gastric veins and the pancreatic vein. Conditions involving the portal vein cause considerable illness and death. An important example of such a condi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appendicular Vein
The appendicular vein is the vein which drains blood from the vermiform appendix. It is located in the mesoappendix and accompanies the appendicular artery. The appendicular vein drains into the ileocolic vein The ileocolic vein is a vein which drains the ileum, colon, and cecum The cecum or caecum is a pouch within the peritoneum that is considered to be the beginning of the large intestine.

Superior Mesenteric Vein
In human anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine (jejunum and ileum). Behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the hepatic portal vein. The superior mesenteric vein lies to the right of the similarly named artery, the superior mesenteric artery, which originates from the abdominal aorta. Structure Tributaries of the superior mesenteric vein drain the small intestine, large intestine, stomach, pancreas and appendix and include: * Right gastro-omental vein (also known as the right gastro-epiploic vein) * inferior pancreaticoduodenal veins * veins from jejunum * veins from ileum * middle colic vein – drains the transverse colon * right colic vein – drains the ascending colon * ileocolic vein The superior mesenteric vein combines with the splenic vein to form the portal vein. Clinical significance Thrombosis of the superior mesenteric vein is quite rare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ileocolic Artery
The ileocolic artery is the lowest branch arising from the concavity of the superior mesenteric artery. It passes downward and to the right behind the peritoneum toward the right iliac fossa, where it divides into a superior and an inferior branch; the inferior gives rise to the appendicular artery and anastomoses with the end of the superior mesenteric artery, the superior with the right colic artery. It supplies the cecum, ileum, and appendix. Branches The inferior branch of the ileocolic runs toward the upper border of the ileocolic junction and supplies the following branches: * '' colic branch of ileocolic artery'', which passes upward on the ascending colon - from the posterior branch of the inferior branch of the ileocolic artery * ''ileocecal'' (some sources acknowledge this division while others do not) ** '' anterior cecal artery'' and ''posterior cecal artery'', which are distributed to the front and back of the cecum The cecum or caecum is a pouch within the pe ...

Ileum
The ileum () is the final section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms posterior intestine or distal intestine may be used instead of ileum. Its main function is to absorb vitamin B12, bile salts, and whatever products of digestion that were not absorbed by the jejunum. The ileum follows the duodenum and jejunum and is separated from the cecum by the ileocecal valve (ICV). In humans, the ileum is about 2–4 m long, and the pH is usually between 7 and 8 (neutral or slightly basic). ''Ileum ''is derived from the Greek word ''eilein'', meaning "to twist up tightly". Structure The ileum is the third and final part of the small intestine. It follows the jejunum and ends at the ileocecal junction, where the terminal ileum communicates with the cecum of the large intestine through the ileocecal valve. The ileum, along with the jejunum, is suspended ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colon (anatomy)
The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system in tetrapods. Water is absorbed here and the remaining waste material is stored in the rectum as feces before being removed by defecation. The colon is the longest portion of the large intestine, and the terms are often used interchangeably but most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal. Some other sources exclude the anal canal. In humans, the large intestine begins in the right iliac region of the pelvis, just at or below the waist, where it is joined to the end of the small intestine at the cecum, via the ileocecal valve. It then continues as the colon ascending the abdomen, across the width of the abdominal cavity as the transverse colon, and then descending to the rectum and its endpoint at the anal canal. Overall, in humans, the large intestine is about long, which is about one-fifth o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cecum
The cecum or caecum is a pouch within the peritoneum that is considered to be the beginning of the large intestine. It is typically located on the right side of the body (the same side of the body as the appendix (anatomy), appendix, to which it is joined). The word cecum (, plural ceca ) stems from the Latin ''wikt:caecus, caecus'' meaning blindness, blind. It receives chyme from the ileum, and connects to the ascending colon of the large intestine. It is separated from the ileum by the ileocecal valve (ICV) or Bauhin's valve. It is also separated from the Large intestine#Structure, colon by the cecocolic junction. While the cecum is usually intraperitoneal, the ascending colon is Retroperitoneal space, retroperitoneal. In herbivores, the cecum stores food material where bacteria are able to break down the cellulose. In humans, the cecum is involved in absorption of salts and electrolytes and lubricates the solid waste that passes into the large intestine. Structure Develo ...
