Masa harina is corn flour that is ground from dried hominy. White or yellow corn is used for making hominy, which is also known as posole or pozole. The corn is boiled in a solution containing powdered lime and is then washed, dried, and ground to form the masa harina.t is used to make cornbread, muffins, pancakes, polenta, and tortillas. Corn flour is very useful for gluten-free quick breads. Because corn flour contains no gluten, it must be blended with wheat flour when preparing yeasted breads.
The Portal Circulation. The liver is unusual in that it has a double blood supply; the right and left hepatic arteries carry oxygenated blood to the liver, and the portal vein carries venous blood from the GI tract to the liver.
One serious complication of portal hypertension is variceal bleeding. When blood pressure increases in the portal vein system, veins in the esophagus, stomach, and rectum enlarge to accommodate blocked blood flow through the liver. The presence of enlarged veins (varices) usually causes no symptoms. (They may be found during an endoscopy exam of the esophagus.) About 50 to 60 out of 100 people who have cirrhosis develop varices in the esophagus.
