Anatomy 6 Gastrointestinal tract Biology Diagrams This Osmosis High-Yield Note provides an overview of Anatomy and Physiology of the Gastrointestinal System essentials. All Osmosis Notes are clearly laid-out and contain striking images, tables, and diagrams to help visual learners understand complex topics quickly and efficiently. Functions of the digestive system Trigger and initiation. The function of the digestive system truly begins within the brain.Whenever the body's energy stores (i.e. blood glucose, protein, or fat stores) fall below a set point, the hunger centres of the hypothalamus are activated. These centres regulate satiety (fullness) and appetite in order to maintain energy homeostasis. The gastrointestinal tract is located within the torso, extending from the mouth to the anus. Its organs are distributed across the head, neck, thorax, abdomen, and pelvic regions. Most of the GI tract, including the stomach, intestines, and related structures, is housed within the abdominal cavity. Structure and Anatomy
The upper gastrointestinal tract consists of the mouth, pharynx, esophagus, stomach, and duodenum. [13] The exact demarcation between the upper and lower tracts is the suspensory muscle of the duodenum.This differentiates the embryonic borders between the foregut and midgut, and is also the division commonly used by clinicians to describe gastrointestinal bleeding as being of either "upper" or Your digestive system sends food on an incredible journey through your body. Digestion is a complicated process. It involves many organs working together. These organs pull the nutrients from what you eat and drink that your body needs. Keeping your digestive system healthy and working well supports your overall health. The gastrointestinal (GI) system comprises the GI tract and accessory organs. The GI tract consists of the oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, and anal canal. The accessory organs include the teeth, tongue, and glandular organs such as salivary glands, liver, gallbladder, and pancreas. The main functions of the GI system include ingestion and digestion
