Hey, everyone. Let's take a look at this question together, choose which statement is correct regarding the hepatic portal vein. And here we have two statements where statement one says the hepatic portal vein receives blood from the veins of the gastrointestinal system. And statement two says the hepatic portal vein drains the blood from the liver and delivers it the inferior vena cava. And we have to determine whether only statement one is correct. Only statement two is correct. Both statements, one and two are correct or neither statements, one or two are correct. Let's work this problem out together to try to figure out which of the following statements is a correct statement regarding the hepatic portal vein. So in order to of this question, we have to recall what we have learned about the hepatic portal vein to determine if the statement is correct or incorrect. Starting off with statement one, which says that the hepatic portal vein receives blood from the veins of the gastrointestinal system. Well, we know that the hepatic portal vein is part of the hepatic portal system which carries blood from the intestines, gallbladder, pancreas and spleen to the liver, which means that the hepatic portal vein receives blood from the veins of the gastrointestinal system. So statement one is a correct statement which means that we can eliminate answer choice B and answer choice D. Since we have determined that statement, one is a correct statement. Next, we have statement two, which says that the hepatic portal vein drains the blood from the liver and delivers it to the inferior vena cava. Well, we know that the hepatic portal vein carries the blood from the veins of the gastrointestinal system into the liver and not from the liver and it does not deliver it to the inferior vena cava, which means that statement two is a false statement as the hepatic veins are a set of three veins that drain blood from the liver into the inferior vena cava, which means that the hepatic veins carry blood out of the liver and the hepatic portal vein carries the blood into the liver and not from the liver. So only statement one is correct, which means that answer choice. A is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
