Purdue University ANSC 221 - Exam 2
digestion - ANS-all of the chemical and physical changes that food undergoes to be
absorbed
absorption - ANS-takes place as nutrients enter the body from the digestive tract
digestive system - ANS-GI tract: mouth, esophagus, stomach, small/large intestine,
liver, gall bladder, pancreas
mouth - ANS-includes lips, teeth, tongue, salivary glands
prehension - ANS-grasping of food by the lips
prehensile lip - ANS-the top lip that has been split into two sections to help grasp and
take in food
mastication - ANS-the process of chewing, preformed by the teeth
swallowing - ANS-the step of digestion after chewing, preformed by the
tongue/esophagus
true - ANS-True or false? Herbivores only have bottom front teeth
bicarbonate - ANS-____________ is a mouth secretion produced only in ruminants
salivary amylase - ANS-____________ is a mouth secretion produced only in
nonruminants
salivary amylase (enzyme) - ANS-an enzyme that digests amylose (a type of starch)
crop - ANS-an organ present in birds in which food is temporarily stored and is
somewhat softened
monogastric - ANS-has a simple stomach
ruminant - ANS-has a four-chambered complex stomach
, pyloric - ANS-the ______ region of the stomach has a flap that opens and closes the
stomach
stomach - ANS-Functions of this organ of the digestive system include storage and
some chemical digestion
esophageal, cardiac, fundic, pyloric - ANS-What are the four regions of a monogastric
stomach?
proventriculus - ANS-the stomach of a bird
gizzard - ANS-Found in birds: Thick muscular wall; breaks down food mechanically,
instead of teeth
proventriculus (follows) - ANS-The gizzard follows the ______________.
crop (follows) - ANS-The proventriculus follows the _________.
mucin - ANS-lines the stomach to prevent acid from harming it
hydrochloric acid - ANS-activates pepsinogen to pepsin
pepsin - ANS-active form of pepsinogen
pepsin (function) - ANS-digests proteins
lipase - ANS-digests lipids
gastric enzymes - ANS-___________ are inactive when secreted so they don't
consume the cell that makes them
rennin - ANS-coagulates milk
rennin (scouring) - ANS-prevents calves from scouring
intrinsic factor - ANS-aids in the absorption of vitamin B12
HCl, gastric enzymes, mucin, intrinsic factor - ANS-What are the 4 main gastric
secretions?
