(Lienal vein is an old term for splenic vein.) The superior mesenteric vein is a blood vessel that drains blood from the small intestine (jejunum and ileum).
Beside above, what organs does the portal vein drain? The portal vein or hepatic portal vein is a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver.
Subsequently, question is, what does the inferior mesenteric artery supply?
The inferior mesenteric artery (IMA) is a major branch of the abdominal aorta. It supplies arterial blood to the organs of the hindgut – the distal 1/3 of the transverse colon, splenic flexure, descending colon, sigmoid colon and rectum.
What vein drains stomach?
The portal vein is formed by the union of the splenic vein and superior mesenteric vein. It receives additional tributaries from: Right and left gastric veins – drain the stomach.
Where does the hepatic vein drain into?
The hepatic veins are the veins that drain de-oxygenated blood from the liver into the inferior vena cava. There are usually three upper hepatic veins draining from the left, middle, and right parts of the liver.
What is a portal venous system?
The portal venous system refers to the vessels involved in the drainage of the capillary beds of the GI tract and spleen into the capillary bed of the liver. Blood flow to the liver is unique in that it receives both oxygenated and deoxygenated blood.
What is the purpose of hepatic portal system?
The hepatic portal system is a series of veins that carry blood from the capillaries of the stomach, intestine, spleen, and pancreas to capillaries in the liver. Its main function is to deliver de-oxygenated blood to the liver to be detoxified further before it returns to the heart.
What is mesenteric thrombosis?
Mesenteric venous thrombosis occurs when a blood clot forms in one or more of the major veins that drain blood from your intestines. This condition is rare, but it can lead to life-threatening complications without prompt treatment. the superior mesenteric vein. the inferior mesenteric vein. the splenic vein.
What is caval system?
Other names. Porto-systemic anastomosis Portal caval system. A portacaval anastomosis is a specific type of anastomosis that occurs between the veins of the portal circulation and those of the systemic circulation.
Where is the SMV?
The superior mesenteric vein, also known as (SMV) transports blood from the small intestine and the cecum. It follows a path similar to that of the superior mesenteric artery. This vein is located in the abdominal cavity next to the superior mesenteric artery.
What is superior mesenteric artery syndrome?
Superior mesenteric artery syndrome (SMAS) is a digestive condition that occurs when the duodenum (the first part of the small intestine) is compressed between two arteries (the aorta and the superior mesenteric artery). This compression causes partial or complete blockage of the duodenum.
What vascular system directs venous blood to the heart from the rest of the body?
Systemic arteries transport oxygenated blood from the left ventricle of the heart to the rest of the body. Veins. The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.
What part of the body does the mesenteric artery supply?
In human anatomy, the superior mesenteric artery (SMA) arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
What does the mesenteric artery do?
The superior mesenteric artery is a major blood vessel in the digestive system. This artery branches off the abdominal aorta and supplies oxygenated blood to the pancreas and the lower parts of the intestine. This includes the lower duodenum, as well as transverse colon.
What is an IMA in medical terms?
In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal.
How is mesenteric ischemia diagnosed?
Once the diagnosis of chronic mesenteric ischemia is suspected, imaging options for confirmation include ultrasound (US), computed tomography angiography (CTA), magnetic resonance angiography (MRA), and conventional angiography.
What does the gonadal artery supply?
The testicular artery (the male gonadal artery, also called the internal spermatic arteries in older texts) is a branch of the abdominal aorta that supplies blood to the testis. It is a paired artery, with one for each of the testes. It is the male equivalent of the ovarian artery.
What does the internal iliac artery supply?
The internal iliac artery (also known as the hypogastric artery) is the smaller terminal branch of the common iliac artery. It supplies the pelvic walls, pelvic viscera, external genitalia, perineum, buttock and medial part of the thigh.
