Chloragogen cells are cells in annelids that function similarly to the liver in vertebrates.

The cells store glycogen and neutralize toxins, are yellowish in colour due to the presence of yellow granules called chloragosomes and are present in coelomic fluid of some annelids.

These cells are derived from the inner coelomic epithelium, and help in excretory functions, as most commonly demonstrated in earthworms.

They have characteristic vesicular bulging which store and transport substances like glycogen and nitrogenous wastes. They take part in the deamination of amino acids and synthesis of urea.

Silicates taken in along with food are deposited in the chloragogen cells
