2. Key Terms
Small Intestine- part of digestive system where most chemical digestion and absorption takes place takes place
Gallbladder-the organ that stores bile
Liver-largest organ inside the body, its role is to produce bile
Bile-a substance that is produced by liver and it breaks up fat
Pancreas-a triangular organ that lies between the stomach and the first part of the small intestine, the pancreas produces enzymes that flow into the small intestine and help break down starches, proteins, and fats.
Villus-finger like projections that line the small intestine and increase surface area and absorb nutrient molecules
Large intestine-the last section of the digestive system which contains bacteria that feeds on the material passing through. Water is absorbed into bloodstream here and the remaining material is readied for elimination from the body.
Rectum-a short tube at the end of the large intestine, waste material is compressed into a solid form here.
Anus-muscular opening at the end of the rectum, waste material eliminated from the body here

3. The Small Intestine What are the functions of the small intestine?
Absorption of nutrients
Most chemical digestion occurs here
Contains villi that
Increase surface area
And aid in absorption

4. The Liver Located in the upper right portion of abdomen
Largest organ inside the body
Breaks down medicines and eliminates nitrogen from the body
Role in the digestive system is to produce BILE, a substance that breaks up fat particles
Bile flows from the liver
Into the gallbladder, the
organ that stores bile.

5. The Pancreas
Triangular organ that lies between the stomach and first part of the small intestine
Produces enzymes that flow into the small intestine and help break down starches, proteins, and fats
Fiber in food doesn’t get broken down

6. The Large Intestine Last section of the digestive system
Contains bacteria that feeds on material passing through
The material in the large intestine contains water and undigested food
Water is absorbed into the bloodstream
Remaining material is readied for elimination from the body
Ends in a short tube called the rectum where waste material is compressed into a solid form
Waste eliminated from the body through the anus
