Question

Through which vein does the hexacanth of Taenia reaches the heart of the pig?

• A. Post caval vein
• B. Renal vein
• C. Hepatic vein
• D. Precaval vein

Answer 1

The correct option is A Post caval vein

Hexacanth is a larva of taenia releases from oncospheres inside the pig. These free hexacanth larvae pass into the intestine and attach to the intestine and penetrate the intestinal wall with the help of the substances secreted by the penetration glands. Later it enters the hepatic portal vein through which it goes to the liver. From the liver it goes to the heart through post caval vein. So the correct answer is 'post caval vein'.
