Well I do remember reading in my 'Life Science' textbook last year the roundworm has a 2 way digestive system. I believe it goes through the mouth, into the intestines, absorbed in through the body and out the other way. I know for sure a roundworm has a 2 way digestive system. I just read my homework, lol. It says on a worksheet, "Science Explorer Life Science" Roundworms have a two-way digestive system and open at both ends. Hope I helped!
flatworms have incomplete digestive systems and they present extracellular and intracellular complementary digestions. They have sac like digestive system, one opening mouth and anus. Which means they're digestive systems aren't completely grown.

Soft tissues, like those of the digestive system, do not fossilize. Thus, we don't know much of anything about Triceratops's digestive system. We do know that they were herbivorous, however, and that they probably ate relatively fibrous vegetation.
