How does a frogs digestive system differ from a humans?

Answer 1

There are several differences between the human and frog digestive system. There are no villi in the small intestine of a frog. Frogs also have dull teeth used only for chewing and a sticky tongue for catching prey.
A humans digestive system starts with their mouth, enzymes in saliva help food to break down, along with their teeth. A human has villi in their small intestine, a frog does not. A Frog has weak teeth in the back of their mouth to physically break food, a human has it at the front.
A major difference is the lack of villi in a frogs small intestine, and most of the digestion takes place in the small intestine of a frog. Humans have villi and most digestion happens in the stomach.
One main difference between a frogs digestive system and a humans is that frogs have no villi in their small intestines. Another difference is that the human tongue is located at the back of the mouth while the frog's tongue is located at the front of the mouth.
The biggest difference between the human and frog digestive system is the species of animal in which is it in. A human chews its food before pushing it to the stomach, where as a frog tends to swallow things whole.
