Hi my name is Peach! I'm 

going to take you on a 

journey of the digestive 

system. This is Anne's 

mouth! Lets go!

Wow look at Anne's white 

teeth! Those will help her 

chew the food! In the 

mouth there is saliva that 

helps break down starch. 

The saliva comes from the 

salivary glands, they 

make saliva. In the mouth 

there is also a tongue and 

that works with the saliva 

to make the food into a 

ball! Amylase is an 

enzyme that helps break 

down starch into sugar! 

In the most of the 

mechanical digestion 

happens. 

Here we are in the esophagus, this is a 

muscular tube that connects the throat to 

the stomach.Farther down you can see 

the epiglottis, it is a flap that covers the 

windpipe when swallowing food. When 

the epiglottis is open the air goes into the 

trachea which is the main system of air 

tubes in which air passes. Come on lets 

move on!!

Here we are in the stomach, it is a sack that stores and 

helps digest food. The gray puddles are called bile, it is 

a liquid that is produced by the liver that helps digest 

fat. Bile is stored in the gallbladder. Lipase also helps 

digest fat but it is produced in the pancreas. The yellow 

puddles are called chyme, it is food that is not 

completely digested that passes into the duodenum. In 

the stomach digestion takes place, digestion is a 

process by which the body changes food so it can be 

used as energy. Protease is a enzyme that helps digest 

proteins. Come on lets go into the duodenum! But first 

we have to pass through the pyloric sphincter valve 

because that valve connects the stomach to the 

duodenum. The liver is connected to the duodenum. The 

liver is a large, lobed organ that produces bile. 

Here we are in 

the duodenum. 

This is the 

beginning of the 

small intestine 

where most 

chemical 

digestion takes 

place. The 

yellow tube is 

the pancreas 

which produces 

enzymes that 

help digest.   

Here we are in the small 

intestine. It is a long 

coiled tube in which food 

is digested and 

absorbed.   In the small 

intestine there are villi, 

they are finger like 

structures that cover the 

inner wall of the small 

intestine.
