Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Jejunum
Concept:

The small intestine is the primary site of nutrient absorption, but different segments have varying degrees of absorptive capacity.

Formula:

N/A

Solution:

  • The Jejunum is the middle section of the small intestine.
  • It is highly specialized with a massive surface area (villi and microvilli) and is the principal site where almost all types of nutrients (carbohydrates, proteins, lipids, vitamins) undergo their most active absorption into the bloodstream and lacteals.


Why other options are incorrect:

The duodenum is primarily focused on final chemical digestion. The ileum absorbs specific remnants like Vitamin B12 and bile salts. The colon absorbs mainly water and electrolytes.
