1. The Digestive System
Wellness 9

2. Parts of the System

3. DIGESTION
When we eat such things as bread, meat, and vegetables, they are not in a form that the body can use as nourishment. Our food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body. Digestion is the process by which food and drink are broken down into their smallest parts so that the body can use them to build and nourish cells and to provide energy.

Moisten food making it easier to swallow

5. MECHANICAL DIGESTION
Mechanical Digestion takes place in the mouth, where the saliva, teeth, and tongue all play an important role in this digestive process.
This is the portion of digestion that we do voluntarily

6. A Closer Look ESOPHAGUS
Food tube leading from mouth to stomach
Food travels through the esophagus by the process of PERISTALSIS.
Peristalsis
has to do with sets of muscles that cooperate to move both liquid and solid food along the digestive tract. In other word, it pushes food along your esophagus, stomach, and intestine.

7. DID YOU KNOW??????
Peristalsis is what allows a person to swallow while lying down or even upside down.
All eating and drinking should be done in a seated or standing position to avoid any possibility of injury.

8. BACK TO BUSINESS STOMACH
The mechanical action of the muscles in the stomach constrict and relax in a continuous motion blending, whipping, and stirring the stomach's contents into chyme, a pulpy substance that can be handled by the small intestine.
Chyme- a substance made when our food combines with juices and acids from the stomach.

9. ANOTHER TIDBIT
CHYME is what we taste when some of our food comes up unexpectedly, however it does not taste the same as it did when it first went down.

10. BACK TO BUSINESS Small intestine
This is the place where the ultimate destruction of food digestion reaches its completion and where the acidity of chyme is nullified. The nutrients in the food eaten many hours ago have almost been diminished to molecules small enough to be absorbed through the intestinal walls into the bloodstream.

11. FINALLY LARGE INTESTINE
Also known as the COLON
What the large intestine essentially does, is act as a passageway for removal of body wastes
Any solid substances that flow into the large intestine are as a rule indigestible.
