Elderly male
Stomach cancer (Physiology of the Organs
in the Digestive…
- Elderly male
- Stomach cancer
Anatomy of The Digestive Tract
- Oral cavity (mouth)
- Pharynx (throat)
- Esophagus
- Stomach - cardia, fundus, body and pylorus (pyloric sphincter and pyloric orifice)
- Small Intestines - duodenum, jejunum and ileum
- Large Intestines - cecum, colon and rectum
Accessory Structures of The Digestion Tract
- Salivary Glands
- Teeth and Tongue- participate in chewing
- Liver
- Gallbladder - stores secretions of the liver
- Pancreas
Basic Nutrients
- Carbohydrate
- Lipids
- Proteins
- Minerals
- Vitamins
- Water
-
Enzymes ,Nutrients and Locations
- Oral Cavity = Salivary Amilase => Carbohydrate
- Stomach = Pepsin => Protein
= Lingual and Gastric Lypase => Triglycerides
- Pancreas = Pancreatics Amilase=> Carbohydrate
= Pancreatic Lipase=> Triglycerides = Inactive Proteases (Tripsinogen, Chymotripsinogen and Procarboxypeptidase) => Activated digest Protein
= Nucleases => Nucleic Acids
- Small Intestines /Brush Border = Dextrinase and Glucoamiyase=> Oligossacharides
= Maltase => Maltose
= Lactase=> Lactose
=Sucrase => Sucrose
= Dipeptidase=> Dipeptides
= Aminopeptidase => Peptides
= Phosphatase=> Nucleotides
= Nucleosidase => Nucleosides
Organs Bypassed in the Alimentary Tube
- Oral Cavity
- Pharynx
- Esophagus
- Stomach
- Duodenum
-
Chemicals or Enzymes NOT Added to Food
- Salivary Amilase
- Intrinsic factor - needed for absorption of B12 in the Ileum
- Hydrochloric Acid
- Bile
- Pancreatic Juice = pancreatic amylase, lipase, tripsinogen, chymotripsinogen and procarboxypeptidase and nucleases
-
Stomach Cancer
Could Develop =
- Liver Cancer
- Pancreatic Cancer
-
Not Able to Do =
- Mechanical Digestion
- Chemical Digestion
- Mastication
- Bolus
- Peristaltics Contractions
- Gastric Mixing
- Chyme
- Gastric Emptying
- Mixing Chyme with Pancreatic Juice and Bile

-
- Feeding Tube= All of his nutrients will need to be provided.in Liquid Form=>Carbohydrate, Protein, Lipids, Minerals and Vitamins
- Food needs to be broken down, so the Jejunum can absorb all the nutrients fed by the tube.
