Cholecystekinin
Increases bile secretions
Secretin
Increases bicarb production in the pancreas
Gastrin
Increases stomach motility
Leptin
A lipokine that decreases appetite
Somatostatin
- Produced by D cells
- Decreases gastric hormone release
Pepsin
Protease made in the stomach
PPY
- Involved in appetite regulations
- Produced in the intestine
GIP
Slows gastric emptying when undigested carbs and fat are arriving in the small intestine
Ghrelin
Increases appetite
Insulin
Decreases blood sugar; from the pancreas
Glucagon
Increases blood sugar; from the pancreas
What are all the evens that occur in the stomach
- Acid secretion
- Mechanical processing

- Protein digestion
An example of a brush border enzyme would be:
Enteropeptidase

In the mouth
Chief and parietal cells are found in the:
Stomach
Fats and proteins are digested by enzymes manufactures in the:

The parotid glands secrete
Saliva
The substance that emulsifies fats is made by the
Liver
