Question

Fully digested food reaches the liver by
A)Hepatic portal vein
B)Hepatic artery
C)Hepatic vein
D)All the above

Answer 1

Hint: An organ about the size of a football is the liver. On the right side of your belly, it lies just behind your rib cage. For digesting food and ridding the body of toxic substances, the liver is necessary. It is possible to inherit Liver Disease

Complete answer:
There are two blood sources in the liver, the hepatic artery and the portal vein. Oxygen and nutrients are given by the hepatic artery, while the portal vein provides substances consumed for metabolic conversion and/or elimination by the gastrointestinal tract.
Hepatic veins carry oxygen-depleted blood from the liver to the lower vena cava. They also carry blood that has been drained from the colon, the pancreas, the small intestine, and the stomach, and cleansed from the liver.

A short blood vessel that supplies the liver, stomach pylorus, duodenum, pancreas, and gallbladder with oxygenated blood is the common hepatic artery.

The hepatic portal vein (HPV) is an artery in the blood that brings blood to the liver from the gastrointestinal tract, the gallbladder, the pancreas and the spleen. This blood contains nutrients and toxins derived from the content of the digested substance. It is around three to four inches in length and is typically formed behind the upper edge of the head of the pancreas by the convergence of the superior mesenteric and splenic veins.

Hence, the correct answer is option (A)

Note: The hepatic portal system is a network of veins that bring blood to capillaries in the liver from the capillaries of the stomach, intestine, spleen, and pancreas. Its main purpose is to carry deoxygenated blood to the liver before it returns to the heart, to be further detoxified.
