Parts of The Digestive System and Their Functions:

Mouth:
1. Mechanical digestion – making food into small pieces  easier digest
2. Saliva – chemical digestions  carbohydrates  sugar
Amylase  rice and bread
Slimes, food  slide down the esophagus

Esophagus:
Squeezes your food down to stomach.

Stomach:
1. Mechanical digestion – churning food
2. Stores food
3. Chemically digest protein – meat
- Makes acid to help break apart protein (meat)
- Enzyme pepsin

Small Intestine:
Fats – bile from liver/ enzyme lipase
Proteins - finished being digested – pepsin
Carbohydrates – finished being digested enzyme amylase
Digested food  protein, carbohydrates, fats go into your blood

Pancreas:
1. Makes all of your digestive enzymes that go into the small intestine
2. Makes insulin  which causes your cells to suck up the sugar in your blood

Liver:
1. Makes bile, which goes to the small intestine to help digest fat
2. Filters your blood

Large Intestine (Colon):
- Stores undigested waste food
- Absorbs all your water
