So these are the three different types of peptidases that are released by the pancreas. So, let's summarize what we just discussed. So basically, as the acidicine moves into our lumen of the small intestine, it basically activates the release of our secretin and CCK the kylo cystic ianin by the small intestinal glands found in the villi deep along the villi of our small intestine so secrete and stimulates the release of the pancreatic juice, which includes pancreatic amylase, pancreatic lipase and the pancreatic peptidases. Our trypsinogen, which is activated into trypsin by interkinase. We have the chinamatripsinogen, which is activated into chiama tryptin by trypsin, and we have carboxy peptidase. Now, the kylo cysticionin basically activates and stimulates the liver to release the bile.
