Why do our stomach have acid when the liver produces alkaline bile?

( If you ever heard of proton pumps inhibitors…these are drugs that prevent the proton pumps from releasing this acid…like Prilosec, etc. ) As the food moves out of the stomach and into the first part of the intestines…a substance known as secretin makes the intestine more alkaline and it signals the liver to make bile and the pancreas to release bicarbonate from its cells.
