The organs they produce include segmental muscles, nephridia, gonads and gonoducts. |

Torsion in gastropods has the unfortunate result that wastes are expelled from the gut and nephridia near the gills. |
|
Gametes are shed into the coelom and carried outside the body through the nephridia or as a result of the body wall actually rupturing. |
|
Sensory and neurosecretory innervation of the nephridia is thus accomplished by a single neuron, which is thought to modulate nephridial performance. |
|
The nephridia extract the gametes from the coelom and emit them into the mantle cavity. |
|
One or two nephridia discharge to the exterior. |
|
There are two kidneys, or nephridia, in primitive gastropods, such as the archaeogastropods, while, in the advanced forms, one kidney is small or lost. |

Micro-PIXE studies of Cd distribution in the nephridia of the earthworm Eisenia fetida. |
|
Oblique transverse sections, approximately 5 mm thick and including mantle, gills, gonad, digestive gland, nephridia, and foot were taken from each specimen. |
