Hepatic portal system hepatic vein. The hepatic vein subsequently drains into the inferior vena cava. The hepatic artery provides 30 to 40% of the oxygen to the liver, while only accounting for 25% of the total liver blood flow. The rest comes from the partially deoxygenated blood from the portal vein. The liver consumes about 20% of the total body oxygen when at rest. That is why the total liver blood flow is quite high, at about 1 litre a minute and up to two litres a minute. That is on average one fourth of the average cardiac output at rest. Large veins
Adjective phrase "private" placed in post-object position only creates one interpretation. The structure of adjective phrases (and of all other phrase types) can be represented using tree structures. There are two modern conventions for doing this, constituency-based trees of phrase structure grammars and dependency-based trees of dependency grammars. Both types of trees are produced here.

The following trees illustrate head-final adjective phrases, i.e. adjective phrases
