Inferior vena cava receives blood from all of the following except:
Correct answer: B. Hepatic portal veins
- A. Iliac veins
- B. Hepatic portal veins
- C. Renal veins
- D. Hepatic veins
Explanation
The inferior vena cava (IVC) does not receive blood directly from the hepatic portal vein because the hepatic portal vein first drains into the liver. The liver is responsible for filtering and processing the blood from the digestive tract before it returns to the general circulation. If the IVC received blood directly from the hepatic portal vein, this would bypass the liver and the blood would not be filtered or processed. This could lead to problems, such as liver disease.
