.../user-licence-1-1/ Summary: Magnetic resonance imaging showed accumulation of the injected tracers in the kidney. The atrial wall of the Mytilus galloprovincialis could filtrate small molecules (<0.5 kDa), but not larger molecules. Nephridia Glomerular filtration T 1 relaxation...

... galloprovincialis is able to concentrate 15 times more manganese ion in the kidney compared with concentrations in ambient seawater, and has been shown to excrete urine voluntarily. Nephridia Heavy metal T 1 relaxation time Magnetic resonance imaging The excretion system of mussels consists...

...Irene Zerbst-Boroffka; Brita Bazin; Angela Wenning ABSTRACT The transport mechanisms underlying urine formation in leech nephridia were investigated in situ and in isolated preparations using pharmacological, electrophysiological and micropuncture techniques. Canalicular cells, which secrete...

...S. S. Campiglia; S. H. P. Maddrell The distal tubules of the 4th and 5th pairs of nephridia of Peripatus acacioi (Onychophora) absorb ions from the fluid passing through them. Since water follows this movement only to a limited extent, the fluid in the lumen becomes hypo-osmotic. Absorption of ions...
