Bell Peppers (fruit→ sugar-> Carbs)

Mouth

Stomachs

Small intestine

Large intestine

  • Mechanical digestion
  • Chemical action of salivary amylase
  • Causes Breakdown of starches

  • No further breakdown occurs in the stomach
  • Bc amylase does not function in acidic conditions of the stomach
  • However mechanical breakdown still going
  • Peristaltic conditions of the stomach mix carbs into CHYME
  • Chime expelled into small intestine
  • Pancreatic juice breaks carbs down into smaller chains
  • Enzymes secreted by intestinal cells that line the villi
  • The undigested lactose moves to the large intestine where bacteria are able to digest it
  • remaining indigestible carbohydrates are broken down by enzymes released by bacteria in the large intestine
  • Bacterial digestion
  • The short-chain fatty acids are either used by the bacteria to make energy and grow, are eliminated in the fece

  • The teeth begin the mechanical breakdown
  • The salivary glands provide some saliva to aid swallowing and the passage through the esophagus.
  • stomach contractions churn the partially digested protein into a more uniform mixture called chyme
  • Protein digestion in the stomach takes a long time
  • The stomach empties the chyme into the small intestine
  • Majority of digestion occurs here
  • The pancreas secretes digestive juice that contains more enzymes that further break down the protein fragments
  • The muscle contractions of the small intestine mix and propel the digested proteins to the absorption sites
  • Very little protein makes it to the large intestine
