43 hepatic portal vein diagram
The portal venous system is part of the circulatory system. After the oxygenated blood from the hepatic vein and the blood from the portal vein mix in the sinusoids, it travels into a central vein and then drains into the hepatic vein. The mixed blood drains into the inferior vena cava. Through this pathway, the liver is provided with about 40 ... The hepatic portal vein is only about 3 inches (8 cm) long. It receives blood from the following blood vessels: 1) superior mesenteric vein - which collects blood from the stomach, small intestine and the ascending and transverse portion of the large intestine.
The liver has a dual blood supply, receiving most of its blood flow (75%) as deoxygenated blood from the portal vein, and the rest from the hepatic artery. The portal vein is a low-pressure system of valveless vessels which does not autoregulate according to hepatic oxygen demand, but rather according to supply (eg. with meals, the portal vein dilates and increases its flow).

Start studying LABEL VEINS OF HEPATIC PORTAL SYSTEM. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The porta hepatis is a transverse slit in the hilum of the liver that is perforated by the right and left hepatic ducts, hepatic artery, and portal vein. The common bile duct, hepatic artery, portal vein, nerves of the liver, and lymphatics lie enclosed within the layers of the hepatoduodenal ligament (free edge of lesser omentum).
On normal anatomy, typically, the splenic vein (SV) joins the superior mesenteric vein (SMV) anteriorly to the IVC and posteriorly to the pancreatic neck to form the PV, which ascends within the hepatoduodenal ligament, posteriorly to the hepatic artery and common bile duct, toward the hepatic hilum, where it divides into right and left (Fig. 2 a).

The porta hepatis is the central intraperitoneal fissure of the liver that separates the caudate and the quadrate lobes. It is the entrance and the exit for several important vessels including the portal vein, the hepatic artery, the hepatic nervous plexus, the hepatic ducts and the lymphatic vessels. The hepatic portal system is designed to require the digested elements to pass through the liver before entering the general circulation. The digestive organs are then drained by the hepatic portal vein. This vein is created by the conjuncture of the superior mesenteric vein and the splenic vein. HEPATIC PORTAL SYSTEM DIAGRAM The hepatic portal vein is the largest vein in the abdominal cavity. It drains blood from the spleen and the gastrointestinal tract to the liver. The hepatic veins begin at the junction of splenic veins and superior mesenteric. The blood from the cystic veins and the inferior mesenteric gastric veins is also drained by the hepatic vein. The hepatic veins drain directly into the inferior vena cava which feeds into the right atrium of the heart. From there the heart circulates the venous blood to the lungs to become oxygenated before it is sent back to the peripheral tissues. Portal Hypertension: Portal hypertension is an increase in the pressure of the portal vein.

Portal pressure decreases from 09:00 to about 19:00 hours. Interestingly, peak reports of bleeding varicies correspond with 09:00 and 23:00 hours.* Normal hepatic circulation is a high flow - low resistance system. Branches of the portal vein deliver 1000-1500 ml/min of blood into the sinusoids of the hepatic lobules. Normal portal venous ...
