The C shaped duodenum
Intestinal villi
Stercobilin is the breakdown-product of heme moiety of hemoglobin  (moiety = molecular part) in erythrocytes.

Macrophages break down old erythrocytes and break the heme down into biliverdin,

Biliverdin reduces to free bilirubin.

Bilirubin binds tightly to plasma proteins (especially albumin) in the blood stream and is transported to the liver.

In the liver bilirubin is conjugated with glucuronic acid and becomes bilirubin diglucuronide

Bilirubin diglucuronide is secreted into the small intestine as bile.

In the small intestine, bilirubin glucuronide is converted  to colorless urobilinogen.

Urobilinogen that remains in the colon gets reduced to stercobilinogen

Urobilinogen gets oxidized to stercobilin,

Stercobilin is responsible for the brown color of human feces. S

Obstructive jaundice
In obstructive jaundice, no bilirubin reaches the small intestine, and there is no formation of stercobilin. The lack of stercobilin and other bile pigments causes feces to become clay-colored.
