What do you mean by digestive cavity?What are its advantages?
Answers
Answer:
A digestive cavity is a digestive sac with only a single opening. In digestive cavity, food is ingested and eliminated through the same opening (examples would be hydra, marine jellyfish, and Platyhelminthes, i.e. flatworms).
Our digestive system can hold way more food this way, allowing us to extract more nutrients. The second advantage of a complete digestive tract is its efficient absorption of nutrients. Since the digestive tract is a long tube, organisms can house lots of organs.
