Structural Organisation in Animals

Solution:

Septal nephridia are present on both the sides of intersegmental septa of segment 15 to the last that open into intestine. Integumentary nephridia are attached to the lining of the body wall of segment 3 to the last that open on the body surface and pharyngeal nephridia are present as three paired tufts in the 4 th, 5 th and 6 th segments
