THE DIGESTIVE SYSTEMZuri, Rachel and Caleb

Where is the digestive system located?

The digestive system is a bunch of organs located all throughout abdomen.

Major Functions of the Digestive System

Digestive system starts in your mouth Food goes down a tube called the esophagus to

the stomach food enters the stomach where it is mixed with

acid Food goes to the small intestine (where more

chemicals are added to the food) Food travels to the large intestine ( were all the

chemicals are taken away from the food, and it absorbs into the blood cells)

Waste leaves body through the anus

Major organs(mouth)

Digestive system starts in your mouth

Your teeth help chew the food into little particles

your saliva moistens the food enough to swallow

Major Organs(esophagus)

Food goes down the esophagus A long tube that forces the food into

your stomach

Major Organs(stomach)

Stomach is a sack like organ Soaks the food in a acid called

chyme that helps your food digest Size of your fist

Major organs(small intestine)

Food goes to duodenum(the first part of your small intestine), then the jejunum( the part of the small intestine),finally to the ileum(the end)

bile, pancreatic enzymes (chemicals) help the food break down even more

Major organs(large intestine) Food finally goes to large intestine Water, electrolytes, and chemicals

are taken out of food Bacteria is added Nutrients that are needed absorbs

into the blood cells Body gets food

Major organs(exiting)

Waste(left over food not needed) exits the body through the anus

Teamwork with the systems

Digestive system breaks down food so the circulatory system can absorb the food into blood cells and feed the whole body

After digestive system and circulatory system have fed the whole body, excretory system helps the waste not needed exit your body

Teamwork with the systems (continued)

If the digestive system broke down, the circulatory system would have no food to absorb, and body would get hungry and weak

The excretory system would have no leftover waste to dispose(it pretty much would be useless)

Diseases in the digestive system Celiac disease- damages lining in the

small intestine and prevents body from absorbing nutrients that is needed

Crohn’s disease-inflammatory of your intestine caused by bowel buildup

Ways to keep The digestive system healthy Eating vegetables and fruits helps

your digestive system by keeping your stomach from having problems

Make sure you drink a lot of water because it is the main thing that helps your digestive system

Fun Facts

of saliva every day Your small intestine is nearly 20 feet

long Your large intestine is actually way

smaller than your small intestine
