BIOL 3442 UTA Pollock The Digestive System EXAM 3
Content Questions With Complete Solutions
99.5% water 0.5% solutes (ions, mucus, lysozyme, salivary
amylase)
controlled by Autonomic Nervous System (ANS) Correct
Answer What is saliva composed of and controlled by?
Absorption Correct Answer movement of products of
digestion from lumen of GI into blood/lymph
Accessory Digestive Organs Correct Answer teeth, tongue,
salivary glands, liver, gallbladder, pancreas
Ampulla of Vater Correct Answer Connection of the
pancreatic duct to the common bile duct from liver and gall
bladder
Antrum Correct Answer extends from body; lower portion of
stomach; the end connects w/duodenum of SI via smooth muscle
sphincter called pyloric sphincter
autonomic nervous system Correct Answer Vagus (X) nerve
supplies parasymp fibers to most of GI, causes increase in GI
secretion and motility by increasing activity of ENS neurons
Sympathetic stimuli causes opposite effect by inhibition of ENS
neurons
, Body Correct Answer below fundus; central portion of
stomach
canines and incisors Correct Answer good for
shredding/tearing food
most carnivores have this
Carbonic anhydrase Correct Answer enzyme that catalyzes
the reaction between carbon dioxide and water to form carbonic
acid
CCK (cholecystokinin) Correct Answer released by small
intestine- stimulates gallbladder to release bile, pancreatic juices
slows gastric emptying by contracting pyloric sphincter
Cephalic Phase Correct Answer the earliest phase of
digestion, in which the brain thinks about and prepares the
digestive organs for the consumption of food
Chief cells Correct Answer secrete pepsinogen and gastric
lipase
circular folds, villi, microvilli Correct Answer What special
features of the small intestine's lamina propia helps increase
surface area for absorption?
Crypts of Lieberkuhn (intestinal glands) Correct Answer
glands that secrete intestinal juice
