Which part of the earthworm is used to absorb nutrients?
Then, they have a gizzard, which through muscular contractions, helps to grind their food down into smaller pieces, like our teeth. After the food passes through the gizzard, it moves into their intestine, where they absorb nutrients (also like us). Any undigested material is excreted as a worm casting.

Do earthworms have complete digestive system?
Earthworms have a complete digestive system, one which has two openings, the mouth and the anus.
What are three tips or techniques used when dissecting an earthworm?
Earthworm Dissection: Internal Anatomy Lay the worm on your dissecting tray with its dorsal side facing up. Use dissection pins to secure each end on the tray. Start your dissection about an inch posterior to the clitellum. Lift up the skin with a pair of forceps and snip an opening with a pair of dissecting scissors.
Put the worm in a bowl of 50% alcohol. The alcohol causes the body and the muscles to relax. Without that, the worm will most likely be stiff and contracted, making for a harder time dissecting.
How do you prepare a live earthworm for dissection?
Place the earthworm on its ventral side. (The ventral side is more flattened than the dorsal side.) Using dissecting scissors, cut through the dorsal body wall posterior to the clitellum and continue the incision toward the prostomium. Be careful not to cut too deep or you will slice into the digestive system.
