PANCREAS

Organ that secretes the most potent digestive enzyme.

LIVER

Organ that secretes Bile, which is secreted into the duodenum during digestion,In the upper right quadrant, Largest organ in human body.

STOMACH

Organ that secretes hydrochloric acid and pepsinogen., Saclike organ that chemically mixes and prepares food received from the esophagus. Makes CHYME for next step in digestion.

DUODENUM

Most digestion and absorbtion take place in this part of the small intestine. The part of the small intestine between the stomach and the jejunum.

CHYME

Stomach mashes the food into a paste. Chyme is the paste., Mixture of stomach fluids and food produced in the stomach by contracting stomach muscles.

VAGUS

Primary autonomic nerve that supplies the GI tract.

ESOPHAGUS

Food tube; from phranyx to stomach.

COLON

Ascending, transverse, sigmoid, descending.

CECUM

Appendix attaches to this structure.

ILEOCECAL

Valve between small intestine and large intestine.

LOWER ESOPHAGEAL SPHINCTER (LES)

Gastric reflux involves this valve., cardiac sphincter, in GI tract, Keeps ingested material moving in one direction, terminal portion of esophagus.

BILE

Mechanically breaks a large fat globule into many smaller fat globulles., A digestive juice secreted by the liver and stored in the gallbladder.

LIPASE

Enzyme that splits fats into fatty acids and glycerol., Pancreatic enzyme necessary to digest fats

CHOLECYSTOKININ

Hormone secreted by the walls of the duodenum, stimulates the pancreas to secrete potent digestive enzymes.

SECRETIN

Hormone secreted by the walls of the duodenum, stimulates the pancreas to secrete a bi-carbonate rich secretion.

INTRINSIC FACTOR

Vitamin Deficiency causing pernicous anemia.

HCI

RESPONSIBLE FOR GASTRIC ph.haridases stage.

AMYLASE

Enzymes that digest carbohydrates/ starches to the disaccaridases stage.

PROTEASE

Tripsinogen and Chymotrypsinogen.

DISACCHARIDASES

Sucrase, An enzyme that digests sucrose into simple sugars. Lactase,enzyme that catalyzes breakdown of lactose into glucose and galactose, Maltase, a digestive enzyme that breaks maltose into glucose.

GASTRIN

Hormone secreted by the stomach; causes the secretion of HCI.

chyme tioTHE EPIGLOTTIS

Covers the epiglottis, thereby preventing the entrance of food and H2O into the respiratory structures.

THE ESOPHAGUS

Is a hollow tube that carries food from the pharnyx to the stomach.

THE STOMACH

delivers chyme to the duodenum at the proper rate.

WHAT WORD IS "DEGLUTITION ASSOCIATED

swallowing.

PARALYTIC ILEUS IS THE

Slowing or cessation of peristalsis.

WHICH OF THE FOLLOWING BEST DESCRIBES THE OMENTUM AND THE MESENTERY

serous membrane.

WHAT IS NOT A FUNCTION OF THE STOMACH

synthesis of plasma proteins especially albumin.

WHAT IS NOT DESCRIPTIVE OF BILE

CLASSIFIED AS A LIPASE

LIPASES, PROTEASES, AND AMYLASES, ARE

DIGESTIVE ENZYMES

FAT DIGESTION IS ACCOMPLISHED BY

BILE AND LIPASE

THE GALLBLADER

CONTRACTS IN RESPONSE TO CHOLECYSTOKININ

WHAT IS NOT A FUNCTION OF THE LIVER

SECRETION OF CHOLECYSTOKININ AND SECRETIN

WHAT BEST DESCRIBES EMULSIFICATION

LARGE FATTY GLOBULE IS MECHANICALLY BROKEN INTO SMALLER FAT GLOBULES.

WHAT ORGAN IS MOST ESSENENTIAL TO LIFE

LIVER

THE PANCREAS

SECRETES THE MOST POTENT DIGESTIVE ENZYME.

WHAT RATE HAS NOTHING TO DO WITH THE APPENDIX

REGULATES THE RATE AT WHICH THE CONTENTS OF THE ILIUM ARE DELIVERED TO THE CECUM.

DUODENUM IS MOST CONCERNED WITH

DIGESTION AND ABSORBTION.

THE COMMON BILE DUCT

EMPTIES BILE INTO THE DUODENUM.

RELAXATION OF THE SPHINCTER OF ODDI ALLOWS

BILE TO ENTER THE DUODENUM FROM THE COMMON BILE DUCT.

AMYLASE AND DISACCHARIDES BOTH

DIGEST CARBOHYDRATES.

THE CANALICULI, HEPATIC DUCT, AND THE CYSTIC DUCT

CARRY BILE.

THE DIGESTIVE END PRODUCTS ARE ABSORBED INTO THE

PORTAL CIRCULATION.

TRYPSIN IS

(ALL THE ABOVE) DIGESTIVE, PANCREATIC, AND PROTEOLYTIC .

WHAT IS MOST RELATED TO THE SMALL INTESTINE

DUODENUM, JUJENUM, ILEUM

THE CHEMICAL AID UNRAVELS DIETARY PROTEIN AND DECREASES BACTERIA IN THE STOMACH

HCI- hydrochloric acid, lowers stomach ph to 1-3. doesn't break down food but kills ingested microorganisms

PTYALIN IS AMYPLASEpathway of blood flow through the portal vein from the gastrointestinal system to the liver, extensive system of veins, begins in the portal circulation veins, goes through the liver, ends in the inferior vena cave, ends the vital branch of systemic circulation, - Takes blood from veins of stomach, small intestines, spleen, pancreas, gallbladder, colon, rectum, and brings it to the liver., _________ is the portion of the circulatory system that uses a large vein (portal vein) to carry nutrient-rich blood from capillaries in the intestines and portions of the stomach to the liver.,

SALIVARY AMYPLASE ( in mouth, released by salivary glands, Begins chemical digestion of carbohydrates by breakingdown of starch, released in mouth, reaks down food with teeth (mechanical digestion).

which of the following is true of cholecystokinin (cck)

(All THE ABOVE), SECRETED BY WALLS OF THE DUODENUM IN RESPONSE TO THE PRESCENCE OF FAT, STIMULATES THE GALLBLADDER TO CONTRACT, THEREBY DELIVERING BILE TO THE DUODENUM, ALSO STIMULATES THE PANCREAS TO SECRETE DIGESTIVE ENZYMES.

THE VAGUS NERVE

IS THE MOST IMPORTANT NERVE OF THE DIGESTIVE TRACT.

WHAT DRUG ACTION INCREASES GUT MOTILITY AND IS THEREFORE USED IN THE TREATMENT OF PARALYTIC ILEUS

ACTIVATES MUSCARINIC RECEPTORS.
