What is the process of digestion in humans and how does it compare to that of a starfish?
Understand the Problem
The question involves understanding the digestive system in humans and starfish, including the types of teeth and their functions. It's likely referencing how food is processed and digested in different organisms, focusing on comparative anatomy.
Answer
Humans use a complex digestive tract; starfish use eversible stomachs for external digestion.
Human digestion involves a complex alimentary canal starting at the mouth and ending at the anus, with various specialized organs for systematic breakdown and absorption of nutrients. Starfish digestion includes eversible stomachs, allowing external digestion before ingesting prey. Both have complete digestive systems but differ in complexity and digestion methods.

More Information
Humans have a monogastric system, whereas starfish have unique external digestion facilitated by their eversible stomachs, emphasizing their adaptation to different ecological niches.
Tips
Confusing the role of eversible stomachs in starfish with typical digestion can occur. Remember, starfish first digest food outside their body.
