• B. Hepatic artery
• C. Hepatic vein
• D. All of the above

Answer 1

The correct option is A Hepatic portal vein

When the veins of any organ of the body does not open in the caval veins or heart but divides into capillaries in any other organ and its blood is transported by veins of that other organ to the heart; then this system is called portal circulation. Hepatic portal system is a portal system, which brings venous blood directly from digestive tract, spleen, pancreas and gall bladder to liver for extraction of nutrients and other metabolites by breaking up into single celled thick capillaries and sinusoids. Hepatic artery and hepatic portal vein enter into liver and divide to form many branches. These branches are also found at the angular part. Its fine branches open into hepatic sinusoids

So, the correct answer is 'Hepatic portal vein'
