Answer 2

Answer:

This type of digestive system is called gastrovascular cavity.

Explanation:

• Animals have developed a variety of digestive processes to help them digest the various nutrients they eat.
• A gastrovascular cavity, which is present in creatures with only one opening for digesting, is the most basic example. This method of digestion is utilized by Platyhelminthes (flatworms), Ctenophora (comb jellies), and Cnidaria (coral, jelly fish, and sea anemones).
• Gastrovascular cavities are normally a blind tube or cavity with a single opening, the "mouth," which also functions as a "anus."
• The mouth is where ingested material enters and travels through a hollow, tubular cavity.
• Digestive enzymes are secreted by cells within the cavity, which help break down the meal.
• The lining of the gastrovascular cavity's cells engulfs the food particles.
