Resumo: | The present study reveals that the excretory system of Glossoscolex paulistus is formed by open holonephridia (exonephridia). It is noticed that different zones are recognized in the nephridial canal, with defined histological and histochemical characteristics: 1) primary canal; 2) lobed canal; 3) first rounded segment; 4) afferent thin segment; 5) efferent thin segment; 6) second rounded segment; 7) ciliary tube; 8) clear canal; 9) pigmented canal; 10) intermediate canal; 11) bladder; 12) terminal canal; 13) nephridiopore. All these regions are intercellular and cilia are found in regions 1, 2, 3, 6, 7 and 13. The connections between afferent and efferent capillary of the vascular supply of the nephridium are made of capillary loops and dilatations which we call glomeruli in this paper. Filtering functions are suggested for the glomerulus. The response of the lobed canal and the first and second rounded segments to Gomori's reaction is strongly positive and this is found to coincide with the largest concentration of glomeruli in the main loops 1 and II, that suggests a higher filtration capacity for the canal and segments. |
