Answer:
a. True
Explanation:
A portal system begins with a set of capillaries and ends with a set of capillaries. Blood comes from one set of capillaries to a a larger blood vessel which drains into another set of capillaries and it is then sent to the heart.
A classic example of portal system is Hepatic portal system. Major function of this system is to deliver nutrients from digested food to liver so that it can be metabolized. Small intestine absorbs nutrients from the digested food. These nutrients enter the blood in first capillary bed present in intestine. The deoxygenated blood flows through Hepatic portal vein to liver. Inside liver the blood passes through second capillary bed and nutrients are released in hepatocytes. These capillaries join the hepatic vein and the blood is sent to heart via inferior vena cava.
