3 天之前 · There are two venous systems that drain abdominal structures – the portal venous system and the systemic venous system. The portal system transports venous blood to the liver for processing, whilst the systemic venous system returns blood to the right atrium of the heart.

2015年12月26日 · The venous drainage of the abdomen is primarily mediated through the portal venous system and the inferior vena cava (IVC). These two systems are separate from each other in their organ drainage, but unite proximal to the IVC’s diaphragmatic hiatus to return blood from the abdomen and pelvis to the right atrium.

The venous drainage of the abdomen is carried out by the portal venous system and the systemic venous system. The portal venous system transports venous blood from the abdominal vasculature to the liver, whilst the systemic venous system returns blood to the right atrium of the heart via the inferior vena cava.

2024年6月2日 · The venous anatomy is divided into systemic and portal venous systems. The key difference between these two systems is the liver. Systemic system: Systemic veins drain directly to the heart through the inferior vena cava without being filtered by the liver first, with most of the venous flow coming from the hepatic veins, kidneys, and lower ...

To understand your portal vein and its job, it helps to learn a bit about your portal venous system. Your portal venous system is a network of veins that drain blood from the following organs in your belly: Small intestine. Large intestine. Stomach. Pancreas. Spleen. Gallbladder.

2023年11月3日 · Venous blood is conveyed by the right, left and short gastric, prepyloric, right and left gastro-omental veins. They all empty into the system of the hepatic portal vein. The intestines have very rich blood supply.

2023年8月28日 · The veins of the anterolateral wall carry deoxygenated blood into the systemic venous circulation and back to the lungs for oxygenation. The superficial abdominal veins dilate and provide a collateral circulation when the portal vein, superior vena cava, or the inferior vena cava get obstructed.

2024年1月16日 · The hepatic portal system is responsible for the venous drainage of many structures within the abdomen. One of the most important structures of this is the hepatic portal vein . The hepatic portal vein is formed by the union of the superior mesenteric and splenic veins and as a result receives nutrient-rich venous blood from the spleen ...

2023年8月8日 · The veins that drain the gastrointestinal organs parallel the major arteries that supply the foregut, midgut, and hindgut, including the celiac, superior mesenteric, and the inferior mesenteric arteries respectively. These veins eventually convene at the portal vein, forming a single venous inflow tract into the liver. The celiac vein …

a) Identify and describe the following planes of the abdomen: transpyloric, transumbilical, subcostal, transtu- bercular, and midclavicular b) Describe the 9 zones created by the subcostal, transtubercular, and midclavicular planes
