Section 5. The Type of Digestive Tract in the Animal Various digestive tract strategies have evolved in different animal groups to aid in the absorption of food molecules. Animals have either: no digestive tract, instead absorption occurs through "body" surfaces (protozoans and sponges, etc.). a sac-like or incomplete digestive tract with only one opening by which food enters and wastes leave (jellyfish, flatworms). a tube-like or complete digestive tract where food enters at one end (called the mouth) and wastes leave at the other end (called the anus), such as annelids, arthropods, chordates (including humans), molluscs, and nematodes. Question 13. What organism is shown with a complete digestive tract? Question 14. What type of digestive tract do humans have?
