2.

3.

Lips and Cheeks • made up of skeletal muscles covered by a skin • keep food in mouth while chewing Palate a. Hard • Covers bone and provides hard surface against which the tongue forces food b. Soft • Ends at uvula • When food is swallowed, soft palate rises as a reflex to close oropharynx Tongue • Contains mucus and serous glands, taste buds • Mixes food and saliva during chewing, forms the food into a mass (bolus) • Initiates swallowing

Saliva • • • 4.

Produced by the salivary gland Moistens food to form bolus Dissolves food substances that begin chemical breakdown of starches

Teeth • Used to chew (masticate) • 32 permanent • embedded at the gingiva

Pharynx

• • • •

Nasopharynx and oropharynx Provide passageway for food, fluids and air Its skeletal muscles move food to the esophagus (peristalsis) It has mucus producing glands that provide fluid for easy swallowing

Esophagus • A muscular tube about 10 inches (25 cm) • Serves as passageway of food • Descends through the thorax and diaphragm 1.

Epiglottis • A flap of cartilage over the top of larynx • Keeps food out of larynx during swallowing

2.

Gastroesophageal sphincter- between esophagus and stomach

Stomach • Located high on the left side of the abdominal cavity • A distensible organ – can hold up to 4 liters • Regions: a. cardiac region b. fundus c. body d. pylorus Pyloric sphincter- controls emptying of the stomach into the duodenum Functions: 1. Storage reservoir for food 2. Mechanical digestion 3. Gastric glands has 4 cells: a. Mucous • Alkaline mucus • Serves as protection against gastric juice b. Zymogemic cells • Pepsinogen (inactive pepsin-protein digesting enzyme) c. Parietal HCI • Increases the activity of protein digesting cells Intrinsic factor • Absorption of vitamin B12 d. Enteroendocrine • Gastrin, histamine, endorphirs, serotonin and sonatoslatin • Gastrin- regulates secretion and motility of the stomach Small Intestine • Starts at pyloric sphincter and ends at ileocecal junction • About 20 feet, one inch by diameter • Divisions: a. Duodenum • Begins at the pyloric sphincter up to around the head of the pancreas • Pancreatic enzymes and bile from the liver enter the small intestine b. Jejunum - middle part Gastro-intestinal System Page 1 of 12

Ileum - terminal end of small intestine Site of chemical digestion and absorption through a. microvilli b. villi c. circular folds Breaks carbohydrates and proteins Enzymes a. Pancreatic amylase • acts on starchy b. Pancreatic enzymes • breaks protein peptides c. Pancreatic lipase • breaks lipids d. Triglycirides • Enters as fat globules • Coated by bile salts and emulsified

Large Intestine (Colon) • Divisions a. Cerum - first part b. Colon o Ascending o Transverse o Descending o Sigmoid Functions: 1. Eliminates indigestible food residue a. Goblet cells produce mucus- facilitates lubrication b. Defecation reflex • stretching of the rectal wall • can be suppressed voluntarily 2.

• expulsion can be attained by Valsalva maneuver Absorbs water, salts and vitamins formed by the bacteria

Liver • Largest gland • Approximately 3 pounds (1.4 kg) • Located at the right side • Made up of lobules (composed of plates of hepatocytes) • Sinusoids - blood filled spaces - lined with Kaupffer cells (phagocytic cells) Functions: 1. Secretes bile 2. Stores fat-soluble vitamins 3. Conjugates bilirubin 4. Stores blood and releases during hemorrhage 5. Synthesizes protein  albumin 6. Synthesizes Prothrombin, Fibrinogen and factors I, II, VII, IX and X 7. Synthesizes fats from carbohydrates and protein  energy or adipose tissue 8. Synthesizes cholesterol  production of bile salts, steroid hormones and plasma membranes 9. Deamination (Amino acid  carbohydrates) 10. Releases during hypoglycemia 11. Takes up glucose during hyperglycemia 12. Detoxification 13. Stores iron as ferritin (necessary for RBC production) Pancreas • Triangular gland extending across the abdomen Functions 1. Produces 1-1.5 L of pancreatic juice everyday 2. Pancreatic juice - clear with high bicarbonate content - can digest all categories of food

A. B.

A.

Description: inflammation of the esophagus; may be acute or chronic. Etiology: • Commonly caused by gastroesophageal reflux disease (GERD) - a syndrome caused by a reflux of gastric contents into the esophagus: a. Lower esophageal sphincter (LES) tone is decreased or relaxed. b. Hiatal hernia c. Emesis d. Delayed gastric emptying time (eg, gastroparesis), common in diabetics. e. Ingestion of hot or corrosive substances f. infectious process (eg, herpes or monilial invasion)

Pathophysiology and manifestations Backflow of HCl / intake of corrosive agents ↓ Damage of the epithelial cells of esophagus Gastro-intestinal System Page 3 of 12

Medical Surgical Nursing ↓ Frequent exposure to chemicals ↓ Pain Signs and Symptoms: 1. N/V 2. Pyrosis (hallmark symptom); may radiate to the back, neck, or jaw. 3. Pain after eating and at night when in a supine position. 4. Pain aggravated by an increase in intraabdominal pressure (eg, straining, lifting). 5. Bleeding 6. Strictures may also occur

B. 1.

3. 4. 5.

Overview of nursing interventions: Medications • Antacids • H2-receptor antagonists – Tagamet (Cimetidine) Diet • Low-fat • Small frequent feedings • no alcohol, no caffeine, no spices • high-Fowler’s during and 1 hour eating Weight reduction Avoid activities that increase intraabdominal pressure. Encourage the patient to: • stop smoking, if applicable. • avoid wearing tight, restrictive clothing

ESOPHAGEAL HIATAL HERNIA

•

Refers to herniation or displacement of a portion of the lower esophagus or the stomach into the thoracic cavity.

Types:

1.

Sliding esophageal hernia (90% of occurrences): herniated portion of the stomach slides back and forth upward through the hiatus secondary to positional changes. • weakening of the muscles of the esophageal hiatus due to the aging process (more than 60%) • Trauma

• •

2.

Hereditary factors Symptoms are associated with gastro-esophageal reflux: 1. Dysphagia 2. Pyrosis 3. Regurgitation 4. Bloating

Rolling / paraesophageal esophageal hernia: fundus and possibly the greater curvature of the stomach herniated alongside the esophagus into the thorax • Occurs less commonly • Complications are high and include gastric volvulus, strangulations, or obstruction. • Symptoms are related to increased intrathoracic pressure: 1. Chest pain 2. Shortness of breath 3. Tachycardia with subsequent impaired gas exchange.

•

Chest pain is characteristic because it mimics anginal pain and usually is not relieved when the patient is recumbent.

B.

Etiology and incidence

1.

Unknown  Infection (H. pylori)  mucosal breakdown  Genetic predisposition  Tobacco use  Ingestion of food or drugs that: a. injure or alter gastric mucosa b. increase hydrochloric acid production Stress  Diseases that alter gastric secretion (eg, pancreatitis, Crohn’s disease)

2.

Duodenal ulcers are thought to occur more prevalent than gastric ulcers and usually occur between the 2nd and 5th decades of life.

C. 1.

Pathophysiology and manifestations Gastric ulcers Injury ↓ Histamine release ↓ Production of HCl by the parietal cells ↓ More injury

Erosion of gastric mucosa

Stricture

Hematemesis and Melena Pyloric obstruction and perforation Gastric ulcers are slow to heal, in part because of poor circulation to the ulcerative site. 2.

3.

4.

Duodenal ulcers. 1. Increased rate of gastric acid secretion (increased number of parietal cells or secondary to vagal stimulation, affects gastric release.) 2. Dumping syndrome reduces the buffering effects of food. 3. Complications include hemorrhage, obstruction, or perforation. Stress ulcers 1. Coffee ground aspirate - hallmark sign 2. Multiple ulcerations felt to be erosions develop secondary to gastric ischemia. S/Sx common to all PUDs: 1. Bloating 2. Belching 3. Nausea Gastro-intestinal System Page 6 of 12

Laennec’s cirrhosis – the most common 1. Caused by the liver’s toxic to alcohol 2. Occurs primarily in middle-aged men Postnecrotic cirrhosis 1. Results from severe liver disease 2. Post - acute viral or chemical hepatitis Primary biliary cirrhosis: inflammation and intrahepatic bile duct destruction. Secondary biliary cirrhosis: chronic partial or complete common bile duct obstruction due to gall stones, pancreatitis or tumor. Cardiac cirrhosis results from right-sided CHF.

Pathohysiology and Manifestations 1. Laennec’s Cirrhosis  Alcohol causes changes  fatty infiltration of the hepatocytes  liver cell necrosis and scarring  as it progresses, inflammation decreases but fibrosis increases  liver distortion  structural (biliary channel) and vascular changes.  Scar tissue formation and irregular hepatocyte regeneration  compression of portal vein  obstruction  portal hypertension



   

Decreased Vitamin ADEK absorption 1. bleeding tendencies 2. poor calcium transport 3. poor skin turgor 4. visual disturbances Depletion of glycogen  hypoglycemia Decreased albumin  decreased COP  anasarca Increased HP  ascites

Decreased bilirubin metabolism  hyperbilirubinemia  jaundice Manifestations postnecrotic - same as Laennec’s cirrhosis. Biliary cirrhosis  Chronic obstruction  increased pressure in the hepatic bile duct  accumulation of bile  areas of necrosis  edema, fibrosis and hepatocellular destruction  scar tissue destruction  hepatomegaly 1. Hyperbilirubenemia 2. Jaundice 3. Pruritus 4. clay-colored stools 5. RUQ pain. 4. Cardiac cirrhosis  Enlarged liver  congested venous blood flow  failure of the heart to pump blood to different areas of the body. 2. 3.



Congestion causes anoxia to the liver  necrosis and fibrosis
