The function of the hepatic portal circulation is to .
a. distribute hormones throughout the body
b. collect absorbed nutrients for metabolic processing in the liver
c. return glucose to the general circulation when blood sugar is low
d. carry toxins to the kidney for disposal through the urinary tract

Option-B

Explanation:

Hepatic portal circulation is a system of veins or a network of veins which acts as a part of the filtration system as it collects the deoxygenated blood from the digestive organs like the intestine, pancreas and the stomach and supplies it to the capillaries of the liver.

The blood in the hepatic veins has the collected nutrients from the digestive tract and since they drain it in the liver where further metabolism will occur to digest the nutrients, therefore, the most appropriate correct option is B,

Thus, Option-B is correct.
