Transit Time |
Entire time it takes for food to get out of GI tract |
|
Digestive Hormones |
Gastrin Ghrelin Secretin Cholecystokinin Gastric Inhibitory Peptide |
|
Gastrin |
Simulates the secretion of hydrochloric acids (HCI) |
|
Ghrelin |
Stimulates appetite Quickens gastric emptying |
|
Secretin |
Slows gastric secretion & movement
Increases water and bicarbonate ions coming from the pancreas |
|
Cholecystokinin |
Makes gallbladder excrete bile |
|
Gastric Inhibitory Peptide |
Decreases gastric secretions and movement |
|
Cephalic Phase |
Senses send signals to brain |
|
Salivary Amalyse |
Breaks down carbs and lysozomes |
|
Journey of Food through GI tract |
Mouth (mechanical and chemical digestion)-> epiglottis closed over passage to lungs-> food travels down pharynx-> goes through esophagus (peristalsis) -> gastroesophageal sphincter-> goes into stomach( gastric secretions start digestion of carbohydrates)(signals go to brain to aid in secretions) -> goes through pyloric sphincter (regulates how much chyme goes to the intestine)-> small intestine (segmentation) (digestion and absorption of many nutrients)-> pancreas and gallbladder (send bile, bicarbonate ions(neutralize the acid that is in chyme) and pepsinogen)large intestine (absorption of water, some vitamins and minerals). |

|
Digestion with pancreatic amalyse |
Digests starches to double sugars |
|
Digestion of fiber |
Can't be digestion by enzymes
Goes to the large intestine |
|
Digestion done by microvilli |
Make double sugars into simple sugars by using enzymes |
|
Digestion by Pancreatic Proteases from microvilli and pancreas |
Makes polypeptides into amino acids |
|
Digestion by bile & pancreatic lipases |
Divides large fat-> pancreatic lipases digest triglycerides |
|
Digestion done by microvilli |
Make double sugars into simple sugars by using enzymes |
|
Digestion by Pancreatic Proteases from microvilli and pancreas |
Makes polypeptides into short amino acids or amino acids-> absorbed by mucosal cells to become single amino acids-> passed to the blood |
|
Digestion by bile & pancreatic lipases |
Divides large fat-> pancreatic lipases digest triglycerides-> short chain fatty acids are absorbed by mucosal cells-> go into blood
Long chain fatty acids combine with bile to divide-> transport particles take absorbed lipids and go directly to the blood with passing through the liver |
