The Liver: Structures and Relation to Alcoholic Cirrhosis (Essay Sample)
1. The liver has a portal vein as well as a hepatic vein. It also has unique exchange blood vessels similar to capillaries, called “sinusoids.” How do these unique structures determine the function of the organ? 2. Cirrhosis leads to scarring and increased hydrostatic pressure in the hepatic portal vein. Explain why this increased venous pressure causes net filtration to increase in the hepatic capillaries, leading to ascites (swollen and fluid-filled interstitial space of the abdomen). 3. Explain why the underproduction of albumin by a cirrhotic liver contributes to excessive filtration, which leads to ascites. Refer again to the forces that determine net filtration pressure in the hepatic capillaries, and to the function of albumins.

The portal vein is a known blood vessel carrying blood from gallbladder, gastrointestinal also spleen, and pancreas to the liver.

Portal Vein cannot be referred to as a usual vein as it conducts the blood to the capillary, which then bends to the liver and not to the heart directly.
On the other hand, Hepatic Veins are blood vessels carrying the blood that contains low oxygen from the liver to the
