Transcript of Copy of Team 9 - Smell, Taste, Gastrointestinal System

Carrots Through George's GI Tract
Taste
5 taste sensations:
sweet
salty
sour
bitter
umami
Age related changes:
Xerostomia (dry-mouth)

TRY THIS!
1. Eat the crackers (to simulates dry mouth).
2. Either eat the bread alone or dunk it in water.
3. Share your experience with the class!
Taste, Smell & Gastrointestinal System
By: Allison Gallant, Chun (Andy) Yip, Julie Zasada, Karen Lee, Marie McNabb, & Kyleen Wong
Smell
Smell is defined as the detection and identification by sensory organs of airborne chemicals
Abnormal loss of smell is negative prognostic factor for specific neurodegenerative diseases

Gastrointestinal Tract
2 divisions: alimentary canal and accessory organs
Functions: digestion, absorbing nutrients and excreting waste

ALIMENTARY:
mouth
pharynx
esophagus
stomach
small intestine
large intestine
ACCESSORY ORGANS & GLANDS:
teeth
tongue
salivary glands
pancreas
liver
gallbladder
Mouth
Chemical and mechanical digestion
32 teeth
Enamel
Dentin
3 pairs of salivary glands
Parotid
Sublingual
Submandibular

Age-Related Changes of the Mouth
Dental Caries
Periodontal Disease
Oral Cancer
Dysphagia
Causes
Risk of Aspiration Pneumonia
Swallow Studies
Esophagus
Esophagus connects the pharynx to the stomach
Peristalsis
Gastroesophageal sphincter

Age-Related Changes of the Esophagus
Stomach
Gastritis
Gastric (peptic) ulcer
Cancer of the stomach
Age-Related Changes of the Stomach
Located in the upper left side of the abdominal cavity
Enzymes are used to aid in the chemical digestion of food
Small Intestine
Accessory Organs
Pancreas
Gallstones
Large Intestine
Case Study
Question 1
Where it all ends...

Major digestive organ that connects the stomach to the large intestine
Longest part of the alimentary canal, consist of 3 parts:
Duodenum
Jejunum
Ileum
Majority of absorption occurs here
Last part of the GI tract
Leads from the small intestine to the rectum
Age-Related Changes of the Large Intestine
Majority of carriers remain asymptomatic
Many lifestyle risk factors
Diagnosis by ultrasonography
Treatment options include:
Surgery
Open cholecystectomy
Laparoscopic cholecystectomy
Medical therapy

Diverticulosis and Diverticulitis:
Diverticulosis = pouches
Diverticulitis = inflammation and infection of pouches
References
Age-Related GI Tract Disorders
MOUTH:
dental caries
periodontal disease
oral cancer
dry mouth

dysphagia
ESOPHAGUS:
cancer of the esophagus
hiatal hernia
gastroesophageal reflux disease (GERD)

STOMACH:
gastritis
gastric (peptic ulcer)
cancer of the stomach
ACCESSORY ORGANS:
pancreas:
cancer of the pancreas
liver:
cirrhosis
gallbladder:
gallstones
SMALL INTESTINE
LARGE INTESTINE
appendicitis
diarrhea
constipation
diverticulosis and diverticulitis
cancer and colon and rectum
hemorrhoids
Q1: Not only does George like eating carrots but he’s also an avid coffee drinker. George has been complaining of a burning sensation in his chest after drinking his coffee and also after eating a large meal. He has also noticed that a sour-tasting acid backing up into his mouth. This has been happening to him for many years. What disorder could George potentially have?
Case Study - Question 2
Q2: One day, George started to experience severe abdominal pain in his left lower quadrant. He also had a high fever and felt very fatigued. The pain was so severe that he went to the emergency department. The doctor in the emergency room ordered a CT-scan. The scan showed inflammation and the formation of pouches in his colon. What is the diagnosis?
