The gastrointestinal (GI) system is a series of hollow organs united in a long twisted tube running from the mouth to the anus called the gastrointestinal tract (GI tract). The hollow organs that make up the gastrointestinal system are the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. The liver, pancreas, and gallbladder are the solid accessory organs of the digestive system. The digestive system is a group of organs that work together to convert food into energy and basic nutrients to nourish the entire body. Food passes through the gastrointestinal tract inside the body which connects all the organs. To achieve the true goal of providing the body with basic nutrients and energy, the other six functions of the digestive system are implemented, such as ingestion, secretion, mixing and movement, digestion, l absorption and excretion.

It begins with the mechanical breakdown of food through chewing by the teeth, the tongue pushes the food to the back of the throat with saliva from the salivary glands. Then saliva breaks down the starch so the food slides down the esophagus. After swallowing, food reaches the esophagus which is part of the upper gastrointestinal tract. The esophagus moves swallowed food toward the stomach using a series of muscles called peristalsis. At the end of the esophagus is the lower esophageal sphincter which opens to allow food to pass into the stomach and closes to trap food in the stomach. Once food is in the stomach, it begins to break down mechanically and chemically with the secretion of hydrochloric acid and digestive enzymes. As soon as the stomach breaks down food, mixing and crushing the small pieces coming from the esophagus, it creates it into a more usable form called chyme. Chyme is the liquid mixture that then enters the duodenum of the small intestine through the pyloric sphincter which is at the lower end of the stomach. The small intestine is made up of three segments which are the duodenum, jejunum and ileum. of the lower gastrointestinal tract. The first section begins with a duodenum, this is the very top segment that carries chyme from the pyloric sphincter of the stomach to the other section of the small intestine. While the chyme is processed to move down the other section, the liver, gallbladder, and pancreas deliver a secretion called bile to the duodenum, facilitating chemical digestion through the common bile duct. The duodenum is a C-shaped section responsible for the breakdown process. This then goes into the jejunum where digestion and absorption occur. It in turn empties into the last section of the small intestine, which carries nutrients into the bloodstream and empties the remainder into the cecum portion of the large intestine, this section is the ileum. The main function of this organ is to further break down the food mixture so that the body can absorb all the nutrients, vitamins, minerals, proteins, carbohydrates and fats. A final stage of the digestive process of the gastrointestinal system is the large intestine which includes the appendix, cecum, ascending colon, transverse colon, descending colon, and sigmoid colon. The cecum is the..
