Quizplus · Accepted Answer

Bilirubin, a breakdown product of hemoglobin, is responsible for the typical brown color of feces. The bilirubin is processed by the liver, secreted into bile, and eventually ends up in the intestines, where it is further modified by bacteria to produce urobilinogen and stercobilinogen, which give feces their characteristic color.
