No, a jellyfish does not have a two-way digestive system. Instead, it has a simple gastrovascular cavity with a single opening that serves both as a mouth and an anus. Food enters the cavity for digestion, and waste is expelled through the same opening. This type of digestive system is characteristic of simpler organisms.
The two main types of digestive systems are the complete digestive system and the incomplete digestive system. A complete digestive system features a one-way tract, allowing for the efficient processing of food from ingestion to excretion, as seen in humans and most animals. In contrast, an incomplete digestive system has a single opening for both ingestion and excretion, typical of organisms like jellyfish and flatworms. These systems reflect different evolutionary adaptations to nutrient processing and absorption.
Planarians are classified underneath the flatworm phyla, and flatworms have two way digestive systems.
Oysters have a two way digestive system. This means that they only have on opening for both food to go in and to come out.
yes
No bats have a one way digestive system. Food goes in the mouth, is digested, and comes out the other end. In two way digestive systems food is taken in and waste is excreted through the same opening.
They have complete digestive system.
One way. An earth worm has both a mouth and anus.
Yes, the respiratory system provides oxygen to the digestive system.
It is part of the digestive system. The digestive system goes from the mouth all the way to the anus.
I am not 100 % sure of this but I believe the digestive system goes from your mouth all the way to your colon so everything in between is a part of the digestive system.
one way digestive system is like the human body, like a conveyor belt, the food goes into the mouth the stomach digests it and then exits the anus. two way digestive system is when a mouth eats the food, it gets digested and gets expelled through the same opening (mouth) (imagine barfing your own poo, yuck!)
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!
