Chicken
Stomach cells that secrete digestive enzymes
chief cells
Disorder in ruminants, usually shortly after calving, in which the stomach becomes twisted
displaced abomassum
Process that is impaired during luminal bloat
eructation
structure that causes milk to bypass the reticulorumen during suckling in young ruminants
esophageal groove
Muscular tube involved in deglutition
esophagus
Anaerobic metabolism of nutrients by microbes
fermentation
Region of the stomach where chief cells and parietal cells are located
fundic region
Disorder in ruminants when bits of wire, nails, etc become trapped in the reticulum
hardware disease
common name for reticulum in ruminants
honeycomb
species that is a psuedoruminant
llama
common name for omassum in ruminants
manyplies
most common form of mechanical digestion
mastication
tongue shaped projections in the rumen that increase surface area for absorption
papilla
stomach cells that secrete HCl
parietal cells
salivary gland found at the base of the ear that secretes a high volume of watery saliva

gathering of food and bringing it to the mouth
prehension
muscular valve at the junction of the stomach and small intestine
pyloric sphincter
function of the esophagus not done in horses
regurgitation
enzyme secreted by the abomasum in ruminants that is used in the cheese making process
rennin
broad mucosal folds found inside the stomch

process believed to have developed as a predator avoidance mechanism in ruminants
rumination
savory taste (i.e. foods high in glutamate)
umami

sublingual - under the tongue
what are the four regions of the pig stomach and where are they located
cardiac - top, away from entrance
esophageal - at entrance to stomach
fundic - bottom, away from stomach exit
pyloric - at exit of stomach
what are the four regions of the ruminant stomach and describe them for identification
rumen - largest section
