THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Bilirubin is the yellowish-brown pigment that gives bile its colour. It is created by the breakdown of old red blood cells by the spleen. Further processing of bilirubin happens within the liver.

Detailed explanation-2: -Infection, fever and stress can cause the spleen to destroy more red blood cells than normal. If this occurs, the skin and whites of the eyes will turn yellow because the hemoglobin level will drop and the bilirubin level will rise. Bilirubin is a chemical made when red blood cells are destroyed.
