All three mean Digestive System
4 main functions of the Digestive System?
Ingestion, digestion, absorption, elimination.
Pareternal nutrition
Pertaining of nutrition through the intestines, not through ingestion.
Mechanical digestion
Digestion through the mouth and stomach
Which sphincter prevents food from entering into the stomach?
Lower esophageal sphincter.
Which sphincter stops acid from entering the bowel?
Pyloric sphincter
Fatty stool
Steatorrhea
Eructation
Belching
Sphincter between the ilium and cecum
Ileocecal valve
Mouth
Mechanically breaks food apart by the action of the teeth; moistens and lubricates food with saliva; food is formed into a bolus, a soft mass of chewed food ready to be swallowed.
Teeth
Used in mastication (chewing)
Salivary glands
Secretes saliva to moisten and lubricate food.
Esophagus
Moves the bolus by peristalsis down the esophagus into the stomach
Stomach
Reduces food to a digestible state; converts the food to a semiliquid state called chyme
Small intestine
Digestion and absorption take place chiefly in the small intestine; nutrients are absorbed and transferred to body cells by the circulatory system
Large intestines
Reabsorbs water from the fecal material, stores, and then eliminates waste from the body via the rectum and anus.
Liver
Changes glucose into glycogen and stored it until needed; changes glycogen back into glucose; desaturates fats;assists in protein catabolism;manufactures bile, stores vitamins, produces heat and detoxifies toxins
Gallbladder
Stores and concentrates bile that has been produced by the liver
Pancreas
Secretes pancreatic juice into the small intestine, contains cells that produce digestive enzymes, produces the hormones in insulin and glucagon
Amylase
Enzyme that breaks down starch. Produced in the salivary and pancreatic
Anabolism
Building up of the body substance in the constructive phase of metabolism
Anorexia
Lack of appetite
Appendectomy
Surgical excision of the appendix
Appendicitis
Inflammation of the appendix
Ascites
Significant accumulation of serous fluid in the peritoneal cavity.
Bilirubin
Orange-coloured bile pigment
Bowel
Intestine
Catabolism
Casting down; in metabolism a breaking down of complex substances into more basic elements
Celiac
Pertaining to the belly
Cheilosis
Abnormal condition of the lip as seen in riboflavin and other B-complex deficiencies
Cholecystectomy
Surgical excision of the gallbladder
Cholelithiasis
Gallstones
Cholecystitis
Inflammation of the gallbladder
Cirrhosis
Chronic liver disease
Colectomy
Surgical excision of part of the colon
Colon cancer
Malignancy of the colon. Colorectal cancer
Colonoscopy
Thin, lighted flexible instrument, that is used to view the interior of the colon during a colonoscopy.
Colonoscopy
Visual examination of the colon
Colostomy
Literally means the creation of a new opening into the colon.
Constipation
Infrequent passage of unduly hard and dry feces;difficult defecation
Crohn’s disease
Chronic autoimmune disease that can affect any part of the gastrointestinal tract, but most commonly occurs in the ileum
Defication
Evacuation of the bowel.
Deglutition
Act or process of swallowing
Dentalgia
Pain in the tooth; toothache
Diarrhea
Frequent passage of unformed watery stools
Diverticulitis
Inflammation of the diverticula in the colon
Dyspepsia
Difficulty in digestion; indigestion
Dysphasia
Difficulty in swallowing
Emesis
Vomiting
Enteric
Pertaining to the small intestine
Enzyme
Protein substance capable of causing rapid chemical changes in other substances without being changed itself
Epigastric
Pertaining to the region above the stomach
Eructation
Belching
Flatus
Bloating. Expelling gas from the anus
Gastrectomy
Surgical incision of a part of or the whole stomach
Gastroenterology
Literally means this study of the stomach and intestines
Gastroesophageal reflux disease (GERD)
Condition that occurs when the muscles between the esophagus and the stomach, the lower esophageal sphincter, is weak or relaxes , inappropriately, allowing the stomach’s contents to back up into the esophagus
Gavage
To feed liquid or semiliquid food via a tube (stomach or nasogastric)
Gingivitis
Inflammation of the gums
Halitosis
Bad breath
Hematemesis
Vomiting blood
Hematochezia
Passage of stools that contain red blood
Hepatitis
Inflammation of the liver
Hepatoma
Tumor of the liver
Hernia
Abnormal protrusion of an organ or a part of an organ through the wall of the body cavity that normally contains it.
Hiatal hernia
Occurs when the upper part of the stomached moves up into the chest through a small opening in the diaphragm
Hyperalimentation
Intravenous infusion of a hypertonic solution to sustain life; used in patients who’s gastrointestinal tracts are not working properly.
Hyperemesis
Excessive vomiting
Ileostomy
The surgical creation of a new opening through the abdominal wall into the ilium.
Irritable bowel syndrome (IBS)
Disorder that interferes with the normal functions of the large intestine (colon)
Labial
Pertaining to the lip
Laparotomy
Surgical incision into the abdomen
Lavage
To wash out a cavity
Laxative
Substance that acts to loosen bowels
Mastication
Chewing
Nausea
