1. The Digestive System
By Sofia

2. Where does the food digestion begin????
Digestion, the breaking down of food into small molecules that will be absorbed into our bloodstream begins when you put food in your mouth and begin to chew.
Your teeth help to break the food apart, saliva helps to soften the food and your tongue helps to push the food into your throat when your ready to swallow.

3. Lets Say… Let’s say you eat a hamburger and milk for lunch.
What happens to that hamburger?
Once that hamburger gets into your mouth it gets chewed up into tiny pieces.
The Mouth Starts Everything Moving

4. First Step Your teeth are very important
Your digestive system will work for the next few hours breaking up that hamburger into nutrients that your body can use.
First the hamburger will be made into smaller pieces by chewing with your teeth

5. Saliva
You know when your about to have dinner and you smell that wonderful smell. Your stomach growls and saliva in your mouth that’s digestion starting.
When you eat, the saliva breaks down the chemicals in the food, which helps make the food mushy. Your tongue helps pushing the food around while you chew with your teeth.

6. Journey to the bottom of the throat
How does that Hamburger get to your Stomach??
Well it has to go through something
It goes down your throat!!!!!
How does it get down???
There are muscles in your throat that push the hamburger down

7. The Stomach The stomach physically moves The stomach also squirts acid
The stomach is like a balloon
It shrinks when empty and grows when full
The stomach mixes food before going on to the rest of the body
The stomach is about 12 inches long and is 6 inches wide at its widest point.

8. Small Intestine It is more than 6 meters long
It has three sections, the duodenum, jejunum and ileum
The jejunum is the 1-2 m long, coiled mid-section
The ileum is the final portion of the small intestine, which leads into the large intestine.

9. Large Intestine
The large intestine turns the food you don’t need into stool
The large intestine is about 1.5 m long
The large intestine reabsorbs water and maintains the fluid balance of the body, absorbs certain vitamins, processes undigested material, stores waste before it is thrown away

10. Diverticular Diverticular disease is common among the older people.
Diverticulitis are pea-shaped pouches that forms in the colon wall.
Diverticular disease is common among the older people. Estimates are that 30 to 40 percent of North Americans over age 60 have this problem.

11. Leaky Gut Syndrome
Leaky gut syndrome is the name given for the condition that allows larger food particles to pass through the gut wall.
Ordinarily, only properly digested food goes through the intestinal wall.
When this wall is damaged, larger particles, such as partially digested food and toxins, pass through.
The body does not recognize them and activates the immune system to search and destroy. The result is inflammation.

12. Ulcerative Colitis
Ulcerative colitis is a disease that causes inflammation and sores, called ulcers, in the lining of the rectum and colon.
Ulcers form where inflammation has killed the cells that usually line the colon, then bleed and produce pus
Inflammation in the colon also causes the colon to empty frequently, causing diarrhea.

13. Facts Digestive problems are the No. 1 problem in North America.
An adult esophagus ranges from 10 to 14 inches in length, and 1 inch in diameter
We make 1 to 3 pints of saliva a day
The stomach's wall is lined with three layers of powerful muscles
In the mouth, food is either cooled or warmed to a more suitable temperature
