digestion - Answer the breaking down process of food to allow absorption; combination of
mechanical, chemical, and microbial actions; continuous processing along alimentary canal
mechanical, chemical, microbial - Answer actions throughout the digestive tract:
chewing - Answer example of mechanical action in the digestive system:
intestinal fluids - Answer example of chemical action in the digestive system:
gut microflora (E. coli) - Answer example of microbial action in the digestive system:
alimentary canal - Answer route from mouth to anus; different between species
monogastric, modified monogastric, ruminant - Answer classification of digestive systems:
monogastric - Answer type of digestive system with one stomach; these animals (humans,
swine) are what they eat - high fat diet = high fat carcass
modified monogastric - Answer type of digestive system with one stomach and specialized
components that aid in digestion; found in horses and birds
cecum - Answer What organ aids in digestion in horses?
crop and gizzard - Answer What organs aid in digestion in birds?
ruminant - Answer type of digestive system with more than one stomach compartment; found
in sheep, cattle, goats, and llamas
mouth, esophagus, stomach - Answer What organs in the monogastric digestive system are
responsible for breakdown?
,small intestine - Answer What is the main absorption organ in the monogastric digestive
system?
duodenum, jejunum, ileum - Answer parts of the small intestine (in order) :
omasum - Answer part of the ruminant digestive tract known as the "Butcher's bible"
omasum - Answer What is the main absorption component of the ruminant digestive tract?
abomasum - Answer part of the ruminant digestive tract considered to be the "true stomach"
because it is essentially the same as the stomach in non-ruminants
founder - Answer condition in which the coffin bone in a horse's foot turns over and causes
the toe to grow upward; caused by too many digestible carbohydrates
colic - Answer condition in horses in which the gut is twisted or blocked
lysine - Answer What amino acid is essential to pigs?
taurine - Answer What amino acid is essential to cats?
12-20 hours - Answer What is the passage rate of monogastrics?
96-120 hours - Answer What is the passage rate of ruminants?
6-8 hours - Answer How many hours a day does rumination occur?
cud - Answer regurgitated bolus
bypass proteins - Answer proteins that are basically scrounged up and used to get as much
nitrogen out of their food as possible
volatile fatty acids and vitamins K and B - Answer Microbes in the ruminant tract break down
proteins to make....
water, mucin, bicarbonate salts - Answer salivary glands secrete:
, water - Answer secretion of the salivary glands that moistens the feed and aids in taste
mechanisms
mucin - Answer secretion of the salivary glands that provide lubrication for swallowing
bicarbonate salts - Answer secretion of the salivary glands that act as a buffer to regulate
stomach pH
salivary amylase - Answer What enzyme is secreted from pigs noses for starch breakdown?
N, P, K - Answer Although no enzymes are secreted in the mouths of ruminants, sources of
these elements are provided:
peristaltic waves - Answer muscular contractions that move ingested material through the
esophagus
horses - Answer What animals have peristaltic waves that only move one way?
esophageal groove - Answer muscle that allows milk to bypass the rumen
30-45 days - Answer How long does it take for the rumen to develop and become functional?
reticulum, rumen, omasum, abomasum - Answer 4 compartments of the ruminant stomach:
rumen - Answer Which compartment of the ruminant stomach produces the most gas?
reticulum - Answer Which compartment of the ruminant stomach is known as the
"honeycomb"?
reticulum - Answer this compartment of the ruminant stomach has walls that are lined with
mucus membrane containing many intersecting ridges which subdivide the surface into a
honeycomb-like surface (increased surface area)
rumen - Answer this compartment of the ruminant stomach is a large, hollow, muscular
compartment which extends from the diaphragm to the pelvis and nearly fills the left side of the
abdominal cavity; walls lined with papillae, no enzymes secreted
