Classes of NutrientsCarbohydratesCarbohydrates: main source of
energyProteinsProteins: used for growth. Made of
amino acids. FatsFats: provide energy (stored) and
help body absorb vitaminsVitaminsVitamins: organic nutrients that help
your body to use other nutrients.

Classes of Nutrients MineralsMinerals: Inorganic nutrients that
regulate many chemical reactions in your body.
WaterWater: Most vital factor for survival, other than oxygen. Water enables chemical reactions to take place in your cells.

EnzymesEnzymes are molecules that speed up
the rate of chemical reactions
They do this without being changed or used up.
Enzymes also speed up reactions by reducing amount of energy necessary for a chemical change to begin.

Digestive Enzymes are:AMYLASE is a starch-degrading
enzyme secreted in the mouth. This enzyme breaks down carbohydrates.
PEPSIN, found in the stomach, causes complex proteins to break down into less complex proteins.
Enzymes are also responsible for MANY chemical reactions in your body---not just the ones involved in digestion!

Your Digestive SystemMouth: Begins chemical &
mechanical digestion, glands in mouth produce saliva, which contains amylase, which breaks down starch MOUT

Your Digestive SystemEsophagus: muscular tube that
connects throat to stomach. Moves food down by squeezing (peristalsis)

Your Digestive SystemStomach: muscular bag where
chemical and mechanical digestion continue; food stays here ~4 hours, changes to chyme

Your Digestive SystemSmall Intestine: tube nearly 7
meters long where digestive juices from liver and pancreas are added; villi absorb molecules from chyme

Your Digestive SystemPancreas: a small organ that
produces substances that stop the action of stomach acid, makes enzymes that break down carbohydrates
PANCREAS

Your Digestive SystemLarge Intestine: absorbs water
from undigested food, where unabsorbed materials become more solid

Your Digestive SystemLiver: produces bile, which is stored
in gall bladder. Bile breaks up large particles of fats into smaller particles.
