reduces risk of diabetes
improves digestive tract health
promotes healthy body weight
in order for fiber to do its best work these three things are needed
adequate fiber and fluid intake
regular physical activity
fat digestion starts in the
mouth
fat absorption occurs in the
small intestine
the salivary glands donate
starch digesting and trace amounts of fat digesting enzymes
the liver manufactures
bile
gallbladder stores
bile until needed
bile duct conducts
bile to small intestine
the pancreatic duct conducts
pancreatic juice into the small intestine
the mouth chews and mixes
food with saliva
the esophagus passes
food to somach
the stomach adds
acid, enzymes and fluid
the stomach churns, mixes, and grinds
food into a liquid mass (bolus)
small intestine secretes enzymes that digest
carbs, fat, and protein
the cells lining the small intestine absorb
nutrients into blood and lymph
large intestine reabsorbs
water and minerals
large intestine passes
