why do carbs stop being processed in stomach
the acid stops the salivary enzymes from functioning (denatures them)
what protects the stomach from its own acid
mucus lining
what is the mucus lining made of
epithelial cells & tissue
carbs are broken by
enzymes

bile is stored in
gallbladder
intrinsic factor
facilitates absorption of b-12 in small intestine
small intestine breaks protein down into
amino acids
small intestine breaks carbs down into
simple sugars
small intestine breaks fats down into
