- Be able to label all organs of the digestive system on a diagram
- Functions of the Digestive System (3)
- Why is digestion necessary?
- Mechanical vs. Chemical Digestion
- big pieces -> small pieces
- enzymes
- Order of organs food passes through in the digestive tract (MESSLA)
- Does mechanical/chemical/both/or no digestion occur in each?
- Enzymes/chemicals present in each organ
- What do each of the enzymes/chemicals break down?
- Functions of each organ (digestion/absorption/elimination)
- Importance of villi
- Where does digestion begin and end?
- Where does the most chemical digestion occur?
- Accessory Organs (Liver, gall bladder, pancreas)
- What does each accessory organ do?
- Where does it's product go?
- Function of bile

Digestive System Organ Function
Digestive Organ
|
Role in the Digestive System
|
|
Mouth
|
Mechanically breaks down food into smaller pieces; Chemically breaks down starch using enzymes
|
|
Esophagus
|
A muscular tube that connects the mouth to the stomach. Food moves down by peristalsis.
|
|
Stomach
|
Most mechanical digestion takes place here; muscular
J-shaped pouch in the abdomen; chemical digestion of protein & carbs
|
|
Small Intestine
|
Most chemical digestion takes place
Absorption of nutrients takes place here
|
|
Large Intestine
|
Water is reabsorbed into the body
Waste is stored and eliminated from the body
|
|
Appendix
|
An extension of the large intestine that serves no known
function.
|
|
Liver
|
The liver produces bile, which breaks down fat
|
|
Gall Bladder
|
Stores bile created by the liver
|
|
Pancreas
|
Produces enzymes that chemically break down food
Enzymes secreted into the small intestine
|
