Digestion system mechanim
When do the two glands in the stomach cells secrete their activity
1. Present of food, which trigger them by the brain to be active
What is muscle that allow the chyme to get to the small intestine
1. Pyloric sphincter
What is use in the mouth to hydrolyze starch into small monosaccharides or sugar
1. Salivary amylase or pyalin
What hormone secreted by the hormonal cell of the duodenum that cause the pancreas to release pancreatic juice
1. Secretin
What occur once the food particle get to the duodenum
1. Secretion of horm occur that result, enzyme from liver, pancreas and small intestine to be secreted their to aid with digestion
Where does most digestion occur and which part
1. Small intestine 2. Duodenum
What part of the nervous system that involve in fight or flight mechanism for example moving away from a explosion there inhbit parasympathetic
1. Sympathetic
Wha happen in the blood to Chylomicrons or the triglycerides and esterified cholesterol are package
1. The are converted to LDL
What is the significant of breaking the chemical bond between digestive material
1. The cell can use it as energy
What prevent food to go in the respiratory track
1. The epiglotis
What is the mechanism of the pancreas involve in digestion
1. The present of the chyme cause the pancreas to secrete pancreatic juice 2. Pancreatic juice 3. The pancreatic juice contain bicarbonate which will increase the PH or neutralize the chyme 4. The pancreatic juice also contain enzyme that is active at a basic PH 5. This activate enterokinase 6. Enterokinase activate trypsonogen to trypson 7. Trypson activate the other enzyme
What happen to fats(fatty acid or monoglyceride) when its passing the mucous lining of the small intestine or the intestinal epithilial cess
1. They enter the epithelial cells and go to the ER and resynthesize into triglyceride to pass through
What is a chyme
1. This is a acidic semifluid mixture result of the food particles
What is perestalis
1. This is involuntary contraction of the smooth muscle
What is absorption
1. This is when the product of digestion is sequece in the circulartory system for the cells as fuel
How is the mucus layer of the stomach
1. Very thick
What is the significant of the epiglotis from the mouth is striated muscle,yet as it get close to the stomach it is smooth muscle
1. Voluntary to involuntary control
Are there bacteria in the small intestine
1. Yes
Where is the pancratic lipase is secreted
1. in the stomach
When does digestion take place
1 The lumen of the elemetary canal
Where is lipase produce
1. 1. Mouth, stomach, and pancrease
What are the fat soluble viatmines
1. A, D, E, K
What neurotransmitter involve in the parasympathetic path way
1. Acetylcholine
What are the water soluble viatimins
1. B, C
What is the part of the large intestine that connected to the small intestine and what other structure one can find
1. Cecum 2. Appendix
What are the three part of the large intestine
1. Cecum, colon and rectum
Where are the cell from that secrete enterokinase to activate the enzyme from the pancreas trypsinogen to activate all the other enzymes of the pancreas
1. Cell of the duodenum
What hormone release by the small intestine in the presence of chyme that cause the release of bile in the gallbladder
1. Cholecystokinin or CCK
What are the triglycerides and esterified cholesterol are package into to get to circulation
1. Chylomicrons
Which part of the small intestine is most of digestion occur
1. Duodenum
What are the three part of the small intestine in order of how food particle would move
1. Duodenum, jejunum, and ileum.
What is the hormone release by the duodenum when someone ate so much fat that cause slow movement of chyme to allow more time to digest of fat
1. Enterogastrone
What is the enzyme in the small intestine serve as a master switch, once activate it cause the activation of trypsinogen to activate the other enzyme and where these activity take place
1. Enterokinase 1. Duodenum
What is connected pharynx to the stomach
1. Esophagus
What are the two glands of the stomach
1. Gastric and pyolric
What present is needed to activate pesiogen that is secreted by a chief cell and why
1. HCl 2. Active(pepsin) at PH of two
Where do some absorbe molecule from the Jejunum and ileum pass to get to the live
1. Hepatic portal circulation
What does the cell of the in the pyloric secrete and function
1. Hormone gastrin 2.Secrete More HCL to break down the food particle futher into a chyme
How does the sympathetic nervous system inhibit digestion in the present of danger and why
1. Inhbit blod flow to the organ 2. So the blood flow can go to the muscle and extriemety to run
Where most of the absorption occur in the small intestine
1. Jejunum and ileum
Where does the chylomicrons or the triglycerides and esterified cholesterol are package into to Chylomicrons get to circulation
1. Lacteals
What does the the pancreas secrete
1. Lipase, trypsinogen, chymotrypsinogen, elastinogen , and carboxypeptidase
What is the ring that guide and allow food to go into the stomach
1. Lower esophagel sphincter 2. Cardiac sphincter
What does the duodenum secrete
1. Maltase 2. Lactease 3. Peptidases and dipeptidase 4. Enterokinase 5. Secretin 6. CCK
What kind of digestion occur in the mouth
1. Mechanical and chemical
What is mechanical digestion and chemical digestion
1. Mechanical invole breaking food into the constiuenet 2. Chemical involve involve breaking bonds by enzymatic cleavage
When is the chemical digestion of fat and carbs start and where does lipid digestion continue
1. Mouth 2. Small instine using bile to increase surface area
Where one would find lipase
1. Mouth, stomach, small intestine
What are the cells that one would find the gastric gland
1. Mucous cell, chief cell, and parietal cell
What is the function of the cell found the gastric gland, 1. Mucous cell, chief cell, and parietal cell
1. Mucous secrete mucus, 2. Chie cell secrete pepsinogen 3. Parital cell secrese HCL
What neurotransmitter involve in the sympathetic nervous system and why it take so long for the side affect to stop or one feel their heart is still beating fast after the occation
1. Neuro ephnerine 2. It is a hormone
what is the tract of the digestive tract
