Extract

The nephridia of Hirudo medicinalis, as is well known to biologists, are in pairs extending from the second to the eighteenth segments (somites). Each nephridium consists of a much convoluted cellular tube. The cells of the tube are perforated by small ducts. The nephridia (“segmental organs”) open externally on the ventral side of the body.
