What is the portal triad of the liver?

The portal triad contains the extrahepatic segments of the portal vein, hepatic artery, and bile ducts. Injury to the portal triad is uncommon but is one of the most difficult to manage traumatic injuries associated with high morbidity and mortality.

How many portal triads does a lobule have?

six portal triads
The liver is a solid organ composed of classical functional units called lobules. Each lobule has six sides with a central vein in the middle of the hexagon and six portal triads at the angles.

What happens in Zone 3 of liver?

zone III cells are more important for glycolysis, lipogenesis and cytochrome P-450-based drug detoxification. This specialization is reflected histologically; the detoxifying zone III cells have the highest concentration of CYP2E1 and thus are most sensitive to NAPQI production in acetaminophen toxicity.

What 3 structures make up the portal triad?

Portal triads are composed of three major tubes. Branches of the hepatic artery carry oxygenated blood to the hepatocytes, while branches of the portal vein carry blood with nutrients from the small intestine. The bile duct carries bile products away from the hepatocytes, to the larger ducts and gall bladder.

What is the hepatic portal triad quizlet?

The portal triad consists of: a branch of the hepatic artery, which carries oxygen-rich but nutrient-poor blood. The portal triad consists of: A branch of the bile duct, which will carry away newly produced bile. Each lobule looks like a spoked wheel.

Where are portal triads located?

liver lobules
Portal areas (also called portal triads or portal canals) are located at the corners of liver lobules. Portal areas are normally surrounded by much larger areas packed with hepatic cords and sinusoids.

What does the portal triad consist of quizlet?

A portal triad consists of two lobes of the liver and the gallbladder. A portal triad consists of an interlobular vein, an interlobular artery, and an interlobular bile duct. jejunum. duodenum.

How many lobes does the liver have quizlet?

Liver is divided into three lobes and four segments based on the blood supply and biliary drainage.

What three tubes are contained in the portal triad of the liver?

The portal triad is a distinctive arrangement around the perimeter of hepatic lobules, consisting of three basic structures: a bile duct, a hepatic artery branch, and a hepatic portal vein branch.

How does Budd-Chiari syndrome affect the liver?

Budd-Chiari syndrome is a condition in which the hepatic veins (veins that drain the liver) are blocked or narrowed by a clot (mass of blood cells). This blockage causes blood to back up into the liver, and as a result, the liver grows larger.
