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)
The digestive tract develops from a central cavity located inside the?

No, a gastrovascular cavity only has one opening. Only an alimentary canal features a mouth and anus.
What type of tissue forms the digestive cavity?
The digestive cavity is primarily lined by epithelial tissue, specifically simple columnar epithelium in most parts of the digestive tract. This type of tissue facilitates absorption and secretion, allowing for efficient processing of food. Additionally, smooth muscle tissue is present in the walls of the digestive cavity, aiding in the movement of food through peristalsis. Together, these tissue types work to form the functional structure of the digestive cavity.
Is the esophagus the first section of the digestive tract?
