The body of an earthworm consists of segments. They are clearly visible on the body of the worm, as it moves thanks to them. There is a blood ring inside each segment of the worm. Also, there is a nerve knot inside each segment. Thanks to this body structure, the earthworm can survive and regenerate some organs after its body has been split in two. But only the part where the belt is located (seal on the body of the worm) can survive. But this does not always happen, but only when the incision has not touched important organs.
