An elderly male patient with stomach cancer recently had a feeding tube inserted into his alimentary
canal to bypass the esophagus, stomach and duodenum. He also tells you that he had his gall bladder
removed several years ago.What does this now mean in terms of his diet, food preparation, and
possible effects on rest of his digestive process?
The salivary amylase which helps break down the bolus to carbs, the salivary lipase, Pepsin, Pepsinogen, Maltase and Lipase are chemicals or enzymes that will not participate in the digestive process.
The liver produces bile. Bile is a yellowish brown liquid that helps to break down fats into tiny droplet.
The salivary gland secrets salivary amylase and lipase to break down carbohydrates and lipids respectively etc.
The esophagus is the passage way of food and air.
The gall bladder store and transport bile produced by the liver.
FUNCTIONS OF THESE ENZYMES
Pancreatic amylase breaks down starch to maltaose
Trypsin activates trysinogen to trypsin
Salivary amylase breaks down carbs in the mouth
Chrymotropsin activates peptide bonds
Lipases break down fats to fatty acids
Nucleases breaks down RNA and DNA to nucleotide
Pepsin breaks down proteins to peptides
Maltase and Lactase breaks down carbs to glucose
The liver consist of hepatocytes
The esophagus consist of the stratified squamous epithelium
The salivary gland consist of mucous and serous cell
The stomach consist of the parietal cell and the chief cell
The digestive tract of the Alimentary canal include the mouth, salivary, pharynx, esophagus,stomach,liver, small intestine(duodenum, jejunum, ileum), large intestine and the rectum
ENZYMES AND WHERE THEY ARE PRODUCED
Basic nutrient include Carbohydrates, Proteins, and Fats
Nucleosidases produced by the small intestine.
Nucleases produced by the pancrease
Lipase produced by the pancreas
Peptidases is produced by the small intestine
Trypsin is produced by the pancreas
Pepsin is produced by the gastric glands
Accessory digestive organ include: Pancreas, liver and gallbladder
Maltase and Lactase produced by the small intestine
Pancreatic amylase produced by the Pancreas
Salivary amylase produced by the Salivary gland
The duodenum, illeum and the jejunum of the small intestine consist of the mucosa, submucosa and the muscular externaris.
The large intestine consist of simple colunmar epithelium and smooth muscle
HCL will not be able to break down proteins
The mouth,esophagus, the pharynx, stomach, liver, duodenum of the small intestine will not be able to participate in the digestive process.
The mouth, esophagus, stomach, pancreas, gallbladder and the duodenum of the small intestine are being bypassed
Without the enzyme in the mouth carbs will not be broken down
Since his gallbladder was removed a while ago, it's possible to say that he was unable to store bile produced by his liver. Remember without bile, fats cannot be broken down to tiny droplet.
Without the break down of proteins, he wont be able to repair his worn out tissues
Without proteins(lack of HCL), no enzymes will be produced in the stomach
The stomach cancer can be as a result of hyper secretion of the cells of the stomach due to presence of the virus.
Plasma membrane, vitamins will be messed up because fats are not broken down by bile.
The inefficiency of the Tcytoxic cell of the lymphatic system could also play a role to the stomach cancer he has.
The small intestine( duodenum) will not be able to absorb food adequately.
