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.
In most people, the portal vein splits into left and right veins before entering the liver. The right vein then branches off into anterior and superior veins. The portal vein supplies approximately 75 percent of blood flow to the liver. The portal vein is not a true vein, which means it does not drain into the heart.
