Bicarbonate is indeed secreted by the pancreas, but it is not part of the organ's endocrine function. Bicarbonate is an alkaline substance that is released into the small intestine as a part of the pancreatic juice during digestion. It helps in neutralising the acidity of the chyme (partly digested food). This is an exocrine function of the pancreas, not an endocrine one.

Lipase is an enzyme, not a hormone, and is part of the exocrine function of the pancreas. It is secreted into the small intestine and helps in the breakdown of fats during digestion. While lipase is indeed produced by the pancreas, it is not related to its endocrine function.

Amylase, like lipase, is an enzyme produced by the pancreas and secreted into the small intestine to aid in digestion. It breaks down complex carbohydrates into simpler sugars. While it is a crucial pancreatic product, amylase is a component of the organ's exocrine function, not its endocrine function.
