enzyme secreted by salivary glands and pancreas that breaks down starch into maltose ( a disaccharide)
the process of wave-like muscle contractions of the alimentary tract that moves food along
located at the base of the esophagus and functions to prevent food materials from entering the esophagus from the stomach
circular muscle that controls the movement of chyme from the stomach to the small intestines and prevents its backflow
important to infants because it curdles the milk they ingest, allowing a longer residence in the bowels and better absorption.
A hormone secreted by the small intestine (duodenum) in response to low pH (e.g., from stomach acid). It promotes the release of bicarbonate from the pancreas to act as a buffer.
precursor of trypsin that is in the pancreas and is activated to trypsin in the small intestine
enzyme that acts in the small intestine to break down protein chains into smaller chains of amino acids
enzymes that complete protein digestion by converting small-chain peptides to amino acids.(secreted by pancreas and cells of small intestine; works in the lumen of the small intestine)
substance produced by the liver and released into the small intestine where it emulsifies fat and raises the pH of the chyme entering from the stomach
Tiny hair-like projections of the cytoplasmic membrane located only in the small intestine to facilitate absorption by increasing surface area.
a digestive hormone secreted by the stomach lining; stimulates the secretion of fluid by gastric glands in the stomach
For very fatty foods, the duodenum releases this hormone to slow down the release of chyme by the stomach. (Fats take longer to digest).
