The integumentary system of an earthworm regulates gas exchange, helps in the excretion of waste, and protects the internal organs from physical damage and pathogens.

Prevent from earthworm
An earthworm's ability to dig through soil is aided by its strong, muscular body and the hydraulic pressure created by its body fluids. The earthworm's setae, tiny bristle-like structures on its body, also help it grip onto soil particles as it moves. These structures are located along the earthworm's body segments.

they dispose waste of the earthworms.
The intestines help carry the earthworm's waste to the anus, where it is expelled from the worm.

Earthworms help by fertilizing the soil with their waste.
The organs of the simple excretory system in earthworms are called nephridia. Each segment of the earthworm contains a pair of nephridia, which function to filter and excrete waste products from the coelomic fluid. The nephridia help maintain osmoregulation and eliminate nitrogenous waste, primarily in the form of ammonia. This efficient system allows earthworms to thrive in their moist soil habitats.
Waste is removed through a designated opening
It can move, it's heart can beat, it can eat, and it can produce waste.
