Explanation:
Detailed explanation-1: -The main source of bilirubin is the hemoglobin released from senescent red blood cells, and the liver serves as its primary site of metabolism and excretion.
Detailed explanation-2: -Bilirubin is a waste product produced by the breakdown of red blood cells. Bilirubin is the end-product of heme metabolism; the liver is the site for bilirubin metabolism. Hemoglobin is broken down into heme, which is converted to biliverdin, and finally into unconjugated bilirubin (which is not water-soluble).
