1

These GAGs are found in the extracellular matrix

chondroitin sulfates
hyaluronate
dermatan sulfate

2

This GAG is not found in the extracellular matrix, but is stored in mast cells

heparin

3

Primary function of lacteals in the small intestine

absorption of chylomicrons

4

Loss of inhibitory motor neurons in the LES leading to failure of LES to relax

achalasia

5

Neural endings and receptors that cause an increase in salivary secretion are predominately located on the (blank) side of the cell membrane

basal

6

As saliva passes through the salivary ducts, it is modified. Na+ ions are reabsorbed and K+ is secreted. When salivary secretion is high, there is less (blank) reabsorption.

Na+

7

Concentration of goblet cells would be high in the (blank)

rectum

8

What structure closes upon swallowing to prevent food from entering the trachea?

epiglottis

9

Irritable bowel syndrome occurs when visceral afferent nerve fibers exhibit (blank). It can present as painful constipation of diarrhea.

hypersensitivity

10

Inflammation of the intestinal mucosa of the colon

ulcerative colitis

11

Normal waist circumference for Caucasian men

<102cm

12

The release of (blank) from S cells stimulates the pancreas to release a secretion rich in bicarbonate ions

secretin

13

Proteolytic enzymes secreted by the pancreas are in the inactive form. Trypsinogen is activated by (blank) secreted by the duodenal mucosa and it activates other enzymes.

enterokinase

14

Bicarb ions secreted by the pancreatic ductal cells are produced by the dissociation of carbonic acid. The HCO3- ions are then exchanged for (blank) ions in the lumen

Cl-

15

Basal acid output is increased by...

distention of the stomach followed by activation of afferent and efferent pathways

16

Waist circumference is measured at the level of the (blank)

iliac crest

17

G cells, or gastrin secreting cells, are located in the antral and pyloric regions of the stomach. Gastrin potentiates the release of (blank) from parietal cells

HCl

18

(blank) glands in the fundus of the stomach release gastric acid, pepsinogen, and thick mucous secretions

oxyntic

19

Gastric ulcers are mainly the consequence of this bacteria in the stomach

H. pylori

20

(blank) bile acids are produced by the actions of microorganisms in the lumen of the GI tract

secondary

21

Bile is concentrated in the gall bladder by the absorption of these three things

Na+, Cl-, and water

22

Approximately (blank) percent of vagal fibers are afferent

80%

23

Distortion of the gut mesentary can activate (blank) nociceptive afferent fibers.

splanchnic

24

Many (blank) afferent nerves are likely to be nociceptive.

splanchnic

25

Leptin deficiency is inherited in an autosomal (blank) manner, causes hypogodism, but has normal resting energy expenditure

recessive

26

Asian with a BMI greater than (blank) is "obese"

25

27

At low gastric secretion rates, parietal cells produce a secretion high in NaCl ions. (blank) acid production increases as gastric secretion increases.

HCl

28

Increase in acid production during digestion causes a (blank) tide as the blood pH becomes more basic

Akaline tide

29

An active H+/K+ ATPase on the (blank) side of the parietal cell pumps out H+ into the stomach lumen of the oxyntic glands.

apical

30

The origin of the H+ ions is thought to arise from the dissociation of (blank) in the parietal cell.

H20
