4. Which of the following descriptions is correct for intra-hepatic portal hypertension?

A. Portal vein thrombosis before entering the liver
B. Hepato-petal blood direction
C. Obstruction in the hepatic veins exiting the liver
D. Destruction of the parenchyma due to cirrhosis of the liver



Answer :

Final answer:

Intra-hepatic portal hypertension in the liver is primarily caused by obstructed blood flow due to conditions like cirrhosis, leading to portal hypertension and the formation of shunts bypassing the liver. The hepato-petal blood direction within the liver refers to the flow of blood from the portal triads towards the central vein.


Explanation:

Intra-hepatic portal hypertension refers to the increase in blood pressure within the liver due to obstructed blood flow. This condition is often a result of cirrhosis, where scarring within the liver leads to decreased blood flow through the organ, causing portal hypertension.

One key characteristic is the formation of portal systemic anastomoses, which are shunts that develop to bypass the liver, allowing blood from the intestines to reach the heart without undergoing detoxification in the liver.

Hepato-petal blood direction describes the flow of blood from the portal triads towards the central vein, where the poorly oxygenated blood exits the liver through the hepatic veins.
