Portal Venule

The portal vein or hepatic portal vein is a blood vessel that carries blood from the Each portal venule courses alongside a hepatic arteriole and the two vessels form the vascular components of the portal triad. These vessels ultimately empty

A portal triad is a distinctive arrangement in the liver. It is a component of the hepatic lobule. It consists of the following five structures: proper hepatic artery, an arteriole branch of the hepatic artery that supplies oxygen; hepatic portal vein, a venule branch of the portal vein,

The portal venous system drains blood to the liver from the abdominal part of .. The mechanism involves ova deposition in the portal venules, which incites a

The portal venule and hepatic arteriole both send terminal branches into the acinus (2/3 of the blood supply is portal and 1/3 arterial). They join to form a

It ramifies further, forming smaller venous branches and ultimately portal venules. Each portal venule courses alongside a hepatic arteriole and the two vessels

'Hepatic' means of or relating to the liver, therefore the hepatic portal vein is a These portal venule branches run alongside hepatic arterioles in the spaces

Blood from the branches of the hepatic artery and portal vein travel into the sinusoidal capillaries toward the terminal hepatic venule while bile generated by

B. Blood supply to the liver is only through the hepatic artery. C. Portal tracts in the liver are composed by a hepatic arteriole, a portal venule and a bile ductule.

The hepatic microcirculation derives dual blood supply from the portal vein and the hepatic artery. The terminal portal venules directly connect to the hepatic

Roughly 75% of the blood entering the liver is venous blood from the portal vein. the grouping of bile duct, hepatic arteriole and portal venule is called a portal

carcinoma in the pos- terior aspect of segment. IV, the feed- ing arteries were also analyzed. RESULTS: A venule from the intra- hepatic portal vein to segment.

The blood pressure difference between the portal vein and the terminal portal venule increased compared to control rats. The blood pressure differences

Isolated hepatic arteries are defined as hepatic terminal arterioles that are not accompanied by portal venules or bile ductules and penetrate the liver

Portal and arterial blood flowing through the sinusoids is collected in small branches of hepatic veins (central or terminal hepatic venules) through which the

These include branches of the hepatic artery, the hepatic portal vein (venule) and the intralobular bile ductule. This group of three structures has been called a
