In two way digestive systems food is taken in and waste is excreted through the same opening.

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!
