Study Notes

Digestive Enzymes

  • The salivary glands produce the digestive enzymes amylase and lingual lipase.
  • Amylase breaks down carbohydrates into simple sugars.

Phases of Digestion

  • The cephalic phase of digestion primarily takes place in the brain.
  • The gastric phase of digestion primarily occurs in the stomach.
  • The primary function of the bolus produced during the cephalic phase of digestion is to prepare food for swallowing.
  • The primary function of the gastric phase of digestion is to break down proteins into peptides and amino acids.

Intestinal Phase of Digestion

  • The pancreas is responsible for producing enzymes involved in the intestinal phase of digestion.
  • The duodenum plays a role in the intestinal phase of digestion by receiving bile and pancreatic enzymes to facilitate fat and protein breakdown.

Initiating Digestion

  • The sight, smell, and taste of food initiate the cephalic phase of digestion.
