摘要: Each of the 34 nephridia in leech, Hirudo medicinalis, has its own separate bladder. Urine flows from last portion nephridium, final canal, into bladder through a special inlet which prevents backflow urine. This consists vestibule formed by two serially arranged septa, each with small pore. As no muscles or cilia are associated either inlet, urine flow is passive. leaves an outlet that urethra sphincters at both ends and opening, nephridiopore, ventral skin. The sphincter distinct body wall receive double innervation: retention release therefore active.
