Study Notes

Digestive System

The digestive system is a tube-like structure with a mouth at the anterior end and an anus at the posterior end.
The lining of the digestive tract and glands of the digestive system, such as the liver, are formed from endoderm.

Triploblastic Animals

Triploblastic animals can be classified into three types: acoelomate, pseudocoelomate, or coelomate.
These types are based on the characteristics of the body cavity.
