Chloragog cells (chloragocytes) are a cell type in the intestinal epithelium of annelids (Annelida). The cells store fat and nitrogen products and help in the synthesis of glycogen . They also have a central function in the immune system .

Origin and description

The chloragog cells are formed from the cells of the peritoneum ( coelothelium ) surrounding the intestine and the dorsal vessel, i.e. the outer boundary of the coelom space . They are arranged in the so-called chloragogue tissue, which rests on the animals' intestines and catches the eye of the prepared earthworm as yellowish-white tissue (chloragogue tissue). In the leeches (Hirudinea), in which the coelothelium is dissolved, the chloragog cells as parenchymal-like tissue form mainly the muscle cords, with them the cells are called botryoid cells and the tissue is correspondingly called botryoid tissue.
