Biology notes for class 11 Gastrointestinal Hormones

Biology notes for class 11 Gastrointestinal Hormones In the following article, we will discuss ‘Gastrointestinal Hormones’ from Human Physiology of  Biology Class 11 . Biology class 11 Gastrointestinal Hormones : The food that we ingest is broken down into simple and soluble forms by our digestive system/ alimentary canal/ gastro intestinal tract. This simple and soluble food material is absorbed into the blood stream. Through the blood, the food material is taken up by the various cells of our body and gives energy. Gastrointestinal System can be understood as a system of cells, tissues, organs, and biochemical molecules that help in digestion and absorption of food into the body. GI hormones are chemical messengers that are implicated in many aspects of physiological functions of the gastrointestinal tract, including the regulation of secretion, absorption and digestion, and gut motility. GI hormones are a large family of peptides and are secreted by endocrine cells that are
