Hepatic veins ultimately from numerous central veins of the liver lobules. None of the hepatic veins have valves. The hepatic veins are divided into an upper and a lower group. The upper three drain the central veins from the right, middle, and left regions of the liver and are larger than the lower group of veins. The lower group of from six to twenty smaller hepatic veins come from the right lobe and the caudate lobe, are in contact with the hepatic tissue, and are valveless. All the veins empty into the inferior vena cava at the back of the liver. Budd–Chiari
Nominalized adjective elaborated by Noam Chomsky, it is suggested that inflected adjectives are more likely to be nominalized because they have overtly-marked φ-features (such as grammatical number and gender), which makes them suitable for use as the complement of a determiner. Determiners with unvalued φ-features must find a complement with a valued φ-feature to meet semantic comprehension. In the diagrams below, the determiner is "the", and its complement is either the noun phrase "poor people" or the nominalized adjective "poor". As the frequency of nominalized adjective use decreased, the frequency of structures using the prop-word "one" increased (phrases such as "the large"
