Please choose the best answer from the corresponding letter card, and the corresponding number in the answer will be the black box. 1. * * * which of the following is consistent with the typical pathological changes of portal cirrhosis A. extensive degeneration and necrosis of liver cells B. destruction of normal hepatic lobule structure C. connective tissue hyperplasia D. intrahepatic vascular network reconstruction E. regenerative nodules and lobules formed The correct answer is: E Solution: early liver volume is normal or slightly increased, hard texture. In the later stage, the liver volume was reduced and the weight was reduced. The nodules were similar in size and the diameter of the largest nodules was not over 1.0cm..
