Question

Imagine a patient has blockage of the common bile duct which is preventing any bile from reaching the small intestine (that is, no bile at all is reaching the small intestine). Due to the duct blockage described, you should expect all of the following EXCEPT

A) normal colored stools (or feces) B) decreased micelle formation in the small intestine C) decreased surface area for lipase to act D) decreased absorption of the products of fat digestion

Answer 1

Correct answer is option A

Explanation- due to bile duct blockage, the color of stool will be changed. The normal yellow color of the stool is due to the presence of bilirubin pigment. The bilirubin pigment is formed by the breakdown of hemoglobin . Hemoglobin is broken down in liver to produce bilirubin and this bilirubin is excreted out of liver by bile.

The other options are correct because the main function of bile is to digest the fat. If bile is absent, then fat digestion will be affected. The lipase activity and micelles formation will be reduced.
