Lypolysis occurs in the
small intestine
CCK is released in response to which nutrient in the meal?
fat
Which substance stimulates the release and synthesis of insulin by the beta cells in the
pancreatic islet?
Gastric Inhibitory Peptid (GIP)
Achlorhydria is present when:
the gastric pH never falls below and after
pentagastrin stimulation.
Which part of the GI tract is essential for life?
Small Intestine
Colicky pain is characterized by:
Pain that is interspersed with pain free intervals.
The following are involved in hormonal control of the GI function :
GIP, CCK,
Secretin.
Which gland does not secrete saliva
Submental
All of the following are accessory organs except :
spleen
Food remain the stomach for
2-3 hrs
Enzymes from the gallbladder dump into the
duodenum
In the gastro0intestinal tract all of the absorption occurs in the
small intestine
Which is not a muscular layer of the stomach?
Transverse
GI wall is primarily smooth muscle except:
upper 1/3 of esophagus and anal
sphincter.
Which is not a mucous membrane secretion?
Sweat
Mucous membrane of the GI tract are lined with
cilia
Bile facilitates the digestion of
fat
Function of the gallbladder is to
store bile
Cervical –
parasympathetic to splenic flexure
Mid thoracic T12 –
sympathetic to upper GI
Lumbars –
sympathetic to lower GI
Sacrum –
post ganglionic sympathetic to lower GI
Not a mechanical stimulus of the GI Glands
obstruction of gut
Vagotomy causes what effect upon glandular secretions
decreased glandular
secretions
Myentenz or Aurbach’s plexus controls
GI movement
Not a function of submucosal or meiner’s plexus:
penstalsis
Condition with mainly upper abdominal/ epigastric symptoms such as pain, bloating,
nausea, burping, heartburn, etc….
Dyspepsia
Gastric inhibitory peptide causes:
decreased acidity of the stomach
All may be causes for acites except
duodenal ulcer

is known as
Melenmesis
Odynophagia specifically indicates
pain with swallowing

3 types of ab pain?
Viseral, Parietal, Referred
Most common SE disorder encountered
IBD
2 leading causes of massive lower GI bleeding?
Colonic cancer and hemorrhoids
D-xylose test is for ruling out
Small bowel disease
Which phase of digestion is induced when the gastric meal encounters the duodenal
mucosa?
Intestinal Phase
Most common manifestation of esophageal disease?
Heartburn
Does NOT interfere with formation of Alkaline mucosal barrier in the stomach?
Diet
high in carbs
Protein Digestion –
by pepsin, first in the stomach
Ligament of Treitz –
90% of major GI bleeds
Celiac Artery –
supply of blood to first part of the small and large intestine
Superior Mesenteric Artery –
to splenic flexure
Ulcerative Colitis-
IBD, rectum and left colon
Malabsorption –
increase fecal excretion of fat, deficiency of vitamins, minerals, carbs, proteins.
Gerd –
substernal burning, esophageal reflux, hiatal hernia (worst supine, best sitting)
