The<u> pancreas and stomach </u>of the human digestive tract can be classified as endocrine glands since they produce hormones.
- The endocrine system is a communication system that uses feedback loops to control distant target organs by controlling hormones secreted by internal glands of an organism directly into the circulatory system.
- All endocrine systems in vertebrates are controlled neutrally by the hypothalamus.
- The pancreas performs both endocrine and exocrine functions by secreting fluids directly into the bloodstream and through ducts, respectively.
- The pancreas secretes enzymes, often known as digestive juices, into the small intestine.
- Insulin and glucagon, which control blood glucose levels, and somatostatin, which inhibits the production of insulin and glucagon, are the two primary hormones secreted by the endocrine gland in the pancreas.
- Similarly, When there is food in the stomach, the gastric mucosa, the lining of the stomach, generates a hormone called Gastrin. The hormone induces the formation of pepsin, an enzyme that aids in food digestion, and hydrochloric acid.
