One difference between a gastrovascular cavity and a complete digestive tract?
A gastrovascular cavity is a digestive sac with only a single opening. A complete digestive tract (otherwise known as an Alimentary canal) has two openings (a mouth and anus) between its digestive tubes unlike the gastrovascular cavity in which food is ingested and eliminated through the same opening (example would be hydra)
What is the posterior opening of the digestive tract in a fetal pig?
The posterior opening of the digestive tract in a fetal pig is called the anus. It is the terminal end of the gastrointestinal system where waste material is expelled from the body. The anus is located at the posterior end of the pig, opposite to the mouth which is at the anterior end.
What are the 2 digestive glands that are found outside the digestive tract?
There are two types of glands.Two salivary glands and pancreas.
What are th two types of digestive system?
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.
Roundworms have muscle tissue and a gut with one opening?
Roundworms are multicellular organisms that possess longitudinal muscles and a complete digestive tract, with a mouth and an anus. Their body plan is characterized by a single body cavity that houses their organs, including their nervous and reproductive systems.
Which two actions help to propel a bolus of food through the digestive tract?

What muscles keep digestive tract contents from leaking backwards?
There are two sphincters, one at the end of the esophagus / top of the stomach, and the second at the bottom of the stomach / beginning of the small intestines, which keep digestive contents moving downward through the beginning of the digestive tract.
What Two regions of the digestive tract where mechanical food breakdown occur?
oral cavity and stomach
What is an organ that gets rid of wastes in the body?

What are the two important ways in which the GI tract works?
