Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Large intestine
Concept:

The portal venous system collects blood from specific gastrointestinal organs to send to the liver.

Formula:

None

Solution:

  • The mesenteric veins (specifically the Superior and Inferior Mesenteric veins) are named for their location in the mesentery.


  • They are primarily responsible for draining nutrient-rich, deoxygenated blood from the small intestine and the large intestine (colon).


  • They eventually merge with the splenic vein to form the hepatic portal vein.


Why other options are incorrect:

  • Stomach: Drained mostly by gastric veins.


  • Liver: Drained by the hepatic vein.
