Introduction To The

Digestive SystemHave you ever

wondered how our

digestive system

works? Well, everydaywe get hungry and we

have to eat. We eat

something and it takes

some hours for the

food to go through all

our body, then weeliminate waste.Later,

we get hungry again

and the process starts

all over again.

Parts And Organs Of

The Digestive SystemOur digestive systemorgans are a very

important part of our body.The process of digestion

starts in our mouth.

According to

Enchantedlearning.com,

our mouth breaks food intosmaller pieces and mixes it

with saliva to start the

process of breaking it

down. Our esophagus

takes food to the stomach.

In our stomach *acids and

*enzymes break down thefood. Our small intestine

breaks down food into

nutrients that cells can use.

The large intestine removes

water from food that we

dont need and keeps it

until elimination.

Acids: Any of a class of

substances that release

hydrogen ions when

disolved in water and

can react with a baseto form salts.

Enzymes:A substance

produced by a livingorganism.

What Process Does Our Food Have

When It Passes Through The

Digestive System?

First it starts in the mouth.

Chewing breaks food down and

mixes it with saliva that turns

food into smaller *molecules.Then we swallow the food that

goes down the esophagus into

the stomach. In the stomach

strong acids and juices break

down the food and pass it to the

small intestine. In the small

intestine food breaks down intonutrients. Then the nutrients pass

through the small intestine to the

blood to the cells. In the large

intestine unused parts of the food

go to the large intestine where

water is removed and waste gets

ready for elimination.

Molecules: A group of

atoms bonded together,

representing the smallestfundamental unit of a

chemical compound.

Diseases That Can AffectOur Digestive System

According to YOUR BODY

BATTLES A STOMACH ACHE by

Vicky Cobb, something that can

affect our normal digestion is a

stomach ache. For example a

harmful *bacteria called *E.Coli

can cause a stomach ache. Also in

rare cases parasites can cause a

stomach ache. But most stomach

aches are caused by a *virus. A disorder of our digestive system

is *cancer because we can

develop stomach,colon or intestine

cancer. And it can be really bad

for our digestive system.Also harmful bacteria can affect

our digestive system.

E.Coli: A bacteriumcommonly found inthe intestines ofhumans and otheranimals.

Virus: An infectionor disease

Cancer: The diseasecalled by anuncontrolled divisionof abnormal cells in apart of the body.

Bacterias: Any of alarge group or verysmall one celledorganisms thatreproduce fission or byforming spores.

Keeping Our Digestive

System Healthy

According to FOOD AND

DIGESTION by Steve Parker

*proteins are very important for our

digestive system. We need proteins for

growth, repair and replacement.

Proteins are found in food like meat,

fish, eggs etc.

We also need to eat

*carbohydrates to have energy and to

be active. Foods that have

carbohydrates are: potatoes, bread,

pasta etc. Carbohydrates are very

important for our body.*Fats are better to be

consumed in small amounts.

We also have to eat fruits

and vegetables because they give us

vitamins and minerals.

Proteins: Any of a classof nitrogenous organiccompounds that consistas large molecules.

Carbohydrates: Any of alarge group of organiccompounds occuring onfoods and living tissuesand includingsugar,starch,cellulose.

Fats: A natural oily orgreasy substanceoccuring on animalbodies.

Interesting Facts About TheDigestive System

-Did you know that taste buds are things

in our tongue which help us know what

food tastes like? Taste buds send

-Did you know that your stomach can

stretch to hold the food you eat?-Did you know that food takes 20-45

learned a lot about the

digestive system and its

process. Personally I learned

a lot of new things and

discovered how well the

digestive system works. I

had a lot of fun working on

this project and hopefullyyou have found it as

interesting as I have.
