Digestive System: Chapter 6 Flashcards
Digestive system
Breaks down food physically and chemically
- prepares food for absorption by cells of the body
- eliminates waste functions
Structure Of The Digestive System
Oral Cavity: -teeth -salivary glands Pharynx (throat) Esophagus Stomach Small intestine Large intestine
Accessory Organs Of The Digestive System
- Liver
- Gallbladder
- Pancreas
Oral Cavity
First part of the Digestive tract (mouth + teeth) where the mechanical process of chewing and chemical breakdown of food by salivary secretions initiates the Digestive process
3 Parts Of Small Intestine + Their Location
Duodenum- first segment
Jejunum- second segment
Ileum- third segment
First 4 sections Of The Colon
- Ascending (up)
- Transverse (loop or inward portion)
- Descending (down)
- Sigmoid (straight part, from left to right)
Pancreas
Elongated, flattened organ posterior and slightly inferior(below,lower) to the stomach that produces digestive enzymes and insulin
Gallbladder
Organ on the inferior(below, lower) surface of the liver that stores bile
-cholecyst/o
Gingiv/o
Gums
Lingu/o, gloss/o
Tongue
Orexia
Appetite
Anorexia
Without an appetite
An-without
Orexia- appetite
Dysphagia
Swallowing, eating (that is) painful or difficult
Phagia- swallowing
Postprandial hyperglycemia
Exaggerated rise in blood sugar following a meal
Ex: type 2 diabetes; pancreas can be sluggish about secreting insulin in response to a meal
Prandial- relating to eating food
Gingivitis
Inflammation of the gums
Appendicitis
Inflammation of the appendix
-pain usually localized in the right lower quadrant (RLQ)
Appendicitis: signs + symptoms
- Pain usually In RLQ
- fever, malaise
- diarrhea
- results from obstruction or infection caused by a fecalith (hard mass of fecal matter) or bacteria
Appendicitis: Treatments
Appendectomy- removal of appendix
Diverticulitis
Acute inflammation of diverticulae (pockets; line inside of your intestine)
Diverticulosis
Presence of diverticulae without inflammation
Diverticulitis: signs + symptoms
- tenderness and pain in left lower quadrant (LLQ) of abdomen
- bowel changes, alternating between constipation and diarrhea
Diverticulitis: Treatment
- IV antibiotics and a few days without food or drink (if severe)
- focus on clearing up inflammation and infection, resting the colon
Obstipation
Extreme constipation
Cholelithiasis + Choledocholithiasis
Formation or presence of gallstones within the gallbladder bile ducts
Cholelithiasis + Choledocholithiasis: Signs + Symptoms
- acute onset of upper right quadrant (URQ) abdominal pain that radiates to the shoulder and back
- nausea + vomiting
- classic “attack” called biliary colic, from bile duct obstruction
- following ingestion of large or fatty meals
Cholelithiasis + Choledocholithiasis: Treatments
Nonsurgical:
-extracorporeal shock wave lithotripsy
Surgical:
- laparoscopic cholecystectomy
Cholecystectomy- excision of gallbladder
Anastomosis
Connection between two vessels; surgical joining of 2 ducts, blood vessels, or bowel segments to allow flow from one to the other
Ascites
Abnormal accumulation of fluid in the peritoneal cavity
Borborygmus
Audible abdominal sound caused by passage of gas through the liquid contents of the intestine
Cachexia
State of ill health, malnutrition, and wasting that may occur in many chronic diseases + infections
Dysentery
Diarrhea containing blood + mucus, resulting from inflammation of the walls of the gastrointestinal tract (GI tract), especially the colon
Volvulus
Twisting of the bowel on itself, causing obstruction
Bariatric surgery
Surgical alteration of the stomach as a treatment for morbid obesity
Colostomy
Excision of a diseased part of the colon and creation of a new opening in the abdominal wall, where fecal flow is diverted to a colostomy bag
-creat an opening (mouth) of colon
Polypectomy
Excision of small tumor-like benign (harmless) growths (polyps) that project from a mucus membrane surface
Endoscopy
Visual examination of the interior of organs and cavities with a specialized instrument called a endoscope
Colonoscopy
Examination of the entire length of the colon
Antacid
Counteract or neutralize acidity, usually in the stomach
Antidiarrheals
Control loose stools and relieve diarrhea
Antiemetics
Control nausea + vomiting
Laxatives
Treat constipation
