The document summarizes the multi-step digestive process. The salivary glands, stomach, pancreas, liver, and small intestine all produce enzymes and juices that break down food into smaller molecules like glucose. Bile produced by the liver and pancreas helps digest fats. Digestion is completed as enzymes in the small intestine further break down proteins and carbohydrates.

food.

4. The glands in the stomach lining
produce stomach acid and an enzyme
that digests protein.

5. The pancreas produces a juice
containing several enzymes that
break down carbohydrates, fats,
and proteins in food. The pancreas
delivers digestive juice to the small
intestine through small tubes called ducts

6. The liver produces a digestive juice called
bile. The gallbladder stores bile between
meals. When a person eats, the
gallbladder squeezes bile through the bile
ducts, which connect the gallbladder and
liver to the small intestine. The bile mixes
with the fat in food. The bile acids dissolve
fat into the watery contents of the
intestine, much like how detergents
dissolve grease from a frying pan, so the
intestinal and pancreatic enzymes can
digest the fat molecules.

7. Digestive juice produced by the small intestine
combines with pancreatic juice and bile to
complete digestion. The body completes the
breakdown of proteins, and the final breakdown
of starches produces glucose molecules that
absorb into the blood. Bacteria in the small
intestine produce some of the enzymes needed
to digest carbohydrates.
