Exocytosis is the process used to release insulin from pancreatic cells into the bloodstream.
Pancreatic juice in a frog travels from the pancreas through a duct that empties into the duodenum of the small intestine. When the frog eats, the presence of food in the duodenum triggers the release of pancreatic juice to aid in digestion.
This statement is incorrect. Exocrine glands release their secretions through ducts directly into the external environment or onto a surface, such as the skin or the lumen of a hollow organ, not into the bloodstream.

respiration
Cells release energy through a process called cellular respiration. This process involves breaking down glucose molecules to produce ATP, the cell's main energy source. Cellular respiration occurs in the mitochondria of eukaryotic cells.

The hormone Insulin regulates the body's glucose levels.
The pineal glands releases melatonin into the bloodstream
insulin. Glucagon acts in opposition to insulin by promoting the release of stored glucose from the liver into the bloodstream, leading to increased blood sugar levels. This helps balance blood sugar levels during fasting or times of energy need.
The pancreatic beta islets produce insulin. Alfa cells produce glucagon. Insulin and glucogon produce a homeostatic method to produce normal blood glucose levels.
The pancreas releases insulin into the bloodstream
The release of insulin by the pancreas is an endocrine function. The release of sweat and saliva are exocrine functions.
The intestinal hormone that stimulates the release of insulin from the pancreatic islet cells is called incretin, with the two main forms being glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). These hormones are released in response to food intake and play a crucial role in regulating blood sugar levels by enhancing insulin secretion and suppressing glucagon release.
The body releases insulin after a high-carbohydrate meal to help regulate blood sugar levels. Insulin helps transport glucose from the bloodstream into the cells for energy production or storage. This process prevents blood sugar levels from rising too high, which can be harmful to the body.
To release insulin from the endocrine pancreas cells, the vesicles in the cell need calcium to bind to the internal cell membrane and eject their contents into the blood stream. If a person (or animal) is hypocalcemic (has low blood calcium levels), there isn't enough calcium in the pancreas cell to release the insulin.
Then you must be the pancreas!
The amount of glucose in the bloodstream is something important to track. It becomes even more important when a person is diagnosed as a diabetic. The hormones that control blood sugar are insulin and glucagon.
