Detailed explanation-3: -The nephridium is partitioned in three compartments: a wide sacculus and a nephridial canal formed by a sac-like labyrinth and a bean-like utriculus. The sacculus opens with two different openings to the labyrinth. The labyrinth and the utriculus are connected by a short canal.
