Digestive System

By Maggie

What is the digestive system? The digestive system is the name of the journey that our food takes through our body.

Read on to find out what journey your food takes.

Where does the food start?

The foods first step through your body

starts in your mouth.

How do you break your food down?

The way we break down our food is teeth! They are very, very important in the digestive system as you need them to break down your food.

Incisors

The Incisors are for cutting

your food. .

Incisors cut up

our food just like scissors

Molars When you cut the food with your

incisors the food your eating goes

to the back of your mouth; where it

meets the molars.

There are very

important for chewing

and grinding your food.

Canine

The canines are for ripping

and tearing.

Lions have big canines

because they rip and tear their

meat.

How do we break down our food?

(continued)

Saliva!

Oh yes!!! This strange

substance is one of the most

important things your body

provides. It is full of Amylase

Enzymesmes

Enzymes are small

substances that help you break down your

food.

There are three different types of enzymes that all contribute to

the digestive system.

Enzymes are

produced in the liver.

Amylase

Amylase is part of saliva and is in your mouth. It

is especially designed to break down

carbohydrates.

Did you know that enzymes

are produced by cells?

Protease

Protease is found in your stomach. It is used to break down all of the protein

that you eat.

Handy Hint Remember PROTEASE is

used to break down PROTEIN!!!

Lipase

This final but very important substance is

used for breaking down all of the

fat you eat. It is found in the

small intestine.

This small intestine is where all of the Lipase is found.

Next… So now we've eaten our food where does it go

next?

Right down the

Oeophagus tube.

After That…

Into the stomach

Then, all of the fats are broken down by the Lipase

Then through the …

Then…

Out through

the Anus!!!

Fun Facts!

The reason that faeces is brown and

urine is yellow is all because of dead red

blood cells.

Our salivary glands produce

around 1.5 litres of

saliva each day!

Did you know that your stomach has 52 million glands

in it!
