The last stage of bilirubin involves its processing in the intestine. Conjugated bilirubin is converted by bacteria into mesobilirubinogen and urobilinogen.
Here's a breakdown of the process:
- Initial Stage: Conjugated bilirubin enters the intestine from the gallbladder or liver.
- Bacterial Action: Bacteria in the intestine transform conjugated bilirubin.
- Intermediate Products: The bacteria convert it to mesobilirubinogen and urobilinogen.
- Final Steps:
- Some urobilinogen is reabsorbed into the blood.
- The remaining urobilinogen is either returned to the liver or excreted in urine and feces (Reference: 31-Jul-2024).
Therefore, the end products in the breakdown of bilirubin are urobilinogen and mesobilirubinogen, which are then either reabsorbed, processed further, or excreted.
