Hepatic cells that are found in the organ named liver secretes or produces Bile. This is then stored in a sac named gall bladder.

During the process, the bile is given into the duodenum.

Bile contains the following compounds -

1. Bilirubin as well as Bili - Verdin which are the bile pigments.

2. Salts of bile.
