XIII. 240 In Clepsine..the funnel is surrounded by chloragogenous cells in the interior of the ventral sinus. 1897J. P. Moore in Jrnl. Morphology XIII. 360 Cells..filled with granules which impart..a green-brown color. The coelomic corpuscles have exactly similar characters, and one finds frequent indications of their..budding from the chlorogogen [sic] cells, just as Schaeppi has shown. 1961A. J. Grove et al. Animal Biol. (ed. 6) xii. 204 The chloragogen cells fall into the coelom and after beginning to disintegrate are finally engulfed by phagocytic coelomic corpuscles. Ibid., Coelomic fluid containing ammonia and urea produced by the chloragogenous cells is directed into the nephrostome by ciliary action. 1963R. P. Dales Annelids iv. 88 Tissues referred to as ‘chloragogen’ in polychaetes may also participate in this process. |
