Question

The hepatic portal vein before reaching the liver, joins the?
a. Dorso-lumbar
b. Gonadal veins
c. Anterior abdominal vein
d. Femoro-renal

Answer 1

Hint: The hepatic portal vein divides into two portal veins the left and right on each side further dividing into venous branches and into portal venules. It helps in travelling along hepatic arterioles within the connective tissue in the liver lobules.

Complete answer:
> Option A: Dorso lumbar veins are the veins located inside of the posterior abdominal wall. They usually empty their secretions into the inferior vena cava. They help in receiving blood from the joints of the lumbar spine. Hence, it is an incorrect choice.

> Option B: Gonadal veins are the vessels carrying blood away from the gonads such as testis, ovary towards the heart. Hence, they have no role with liver walls. So, it is the incorrect option.

> Option C: Anterior-abdominal veins helps in the carrying deoxygenated blood from the abdominal wall of superior and inferior epigastric veins and supports the anterior cutaneous nerves. It helps in draining the anterior part of the abdominal wall and some of the diaphragm.
Thus, the hepatic portal system is made by the union of superior mesenteric vein as well as the splenic vein [spleen]. So, it is the correct statement.

> Option D: Femoro-renal are the veins that drain the kidney. These help in connecting the kidney to the inferior vena cava. They purify blood by kidney.

Hence, the correct answer is option (C).

Note: Abdominal vein shows connection or branching with the inferior epigastric vein at the level of navel and drains the part of abdominal wall and diaphragm. Hepatic portal vein known as HPV carries blood from the GIT, gallbladder, pancreas and spleen to the liver.
