Quizplus · Accepted Answer

Bilirubin is a yellow pigment that is formed by the breakdown of heme. Heme is a component of hemoglobin, the protein in red blood cells that carries oxygen. When red blood cells reach the end of their life span, they are broken down in the liver and spleen, and the heme component is converted into bilirubin. Bilirubin is then excreted from the body in the feces and gives stool its characteristic brown color.
