Digestion• Phases Include

1. Ingestion2. Movement3. Mechanical and Chemical

Digestion4. Absorption5. Elimination

Digestive System Organization• Gastrointestinal (Gl) tract

– Tube within a tube– Direct link/path between organs– Structures

• Mouth• Pharynx• Esophagus• Stomach• Small intestine• Large Intestine• Rectum

*

Mouth• Types

– Mechanical (physical)• Chew• Tear• Grind• Mash• Mix

– Chemical• Enzymatic reactions to improve digestion of

– Carbohydrates– Proteins– Lipids

Mouth• Teeth mechanically

break down food into small pieces. Tongue mixes food with saliva (contains amylase, which helps break down starch).

• Epiglottis is a flap-like structure at the back of the throat that closes over the trachea preventing food from entering it.

Esophagus• Approximately 10” long• Functions include:1. Secrete mucus2. Moves food from the throat to

the stomach using muscle movement called peristalsis

• If acid from the stomach gets in here that’s heartburn.

Stomach• J-shaped muscular bag that stores the food

you eat, breaks it down into tiny pieces.• Mixes food with digestive juices that

contain enzymes to break down proteins and lipids.

• Acid in the stomach kills bacteria.• Food found in the stomach is called chyme.

• Acid in the stomach kills bacteria.• Food found in the stomach is called chyme.

*

Small Intestine• Small intestines are roughly 7 meters long• Lining of intestine walls has finger-like

projections called villi, to increase surface area.

• The villi are covered in microvilli which further increases surface area for absorption.

*

* *

Small Intestine• Nutrients from the food pass into the

bloodstream through the small intestine walls.

• Absorbs:– 80% ingested water– Vitamins– Minerals– Carbohydrates– Proteins– Lipids

– Secretes digestive enzymes

*

Large Intestine• About 5 feet long• Accepts what small intestines don’t

absorb• Rectum (short term storage which

holds feces before it is expelled).

Large Intestine• Functions

– Bacterial digestion• Ferment carbohydrates• Protein breakdown

– Absorbs more water– Concentrate wastes

Accessory Organs

• Not part of the path of food, but play a critical role.

• Include: Liver, gall bladder, and pancreas

Liver• Directly affects digestion by producing

bile– Bile helps digest fat

– filters out toxins and waste including drugs and alcohol

*

Gall Bladder

• Stores bile from the liver, releases it into the small intestine.

• Fatty diets can cause gallstones

Pancreas

• Produces digestive enzymes to digest fats, carbohydrates and proteins

• Regulates blood sugar by producing insulin

On a sheet of paper, write the name of each colored organ:

• Green:• Red:• Pink:• Brown:• Purple:• Green:• Yellow:

How’d you do?

• Green: Esophagus• Red: Stomach• Pink: Small Intestine• Brown: Large Intestine• Purple: Liver• Green: Gall Bladder• Yellow: Pancreas

Great Job!

Fun Facts

• HOW LONG ARE YOUR INTESTINES? At least 25 feet in an adult. Be glad you're not a full-grown horse -- their coiled-up intestines are 89 feet long!

• Food drying up and hanging out in the large intestine can last 18 hours to 2 days!

• In your lifetime, your digestive system may handle about 50 tons!!
