digestive system The organs and glands in the body that are responsible for digestion. The digestive system begins with the mouth and extends through the esophagus, stomach, small intestine, and large intestine, ending with the rectum and anus. Other organs in this system include the liver, pancreas, gallbladder, and appendix The digestive system involves organs that turn food into energy and eliminate waste. The energy required for all the processes and activities that take place in our bodies is derived from the foods we ingest Unlike enzymes that are released into your digestive system, hormones are released into your blood and carry messages to other parts of your digestive system. Pancreatic hormones include: Insulin. This hormone is made in cells of the pancreas known as beta cells. Beta cells make up about 75% of pancreatic hormone cells The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract) What Is the Digestive System? Motility, digestion, absorption and secretion are the four vital functions of the digestive system. The digestive system breaks down the foods we eat into energy our bodies can use. The organs that make up the digestive tract include
Description of the digestive system Also known as the gastrointestinal (GI) tract, the digestive system begins at the mouth, includes the esophagus, stomach, small intestine, large intestine (also.. The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body Function of the Digestive System The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts Our body needs food to provide it with energy, vitamins, and minerals. However, in order use food, we must first break it down into substances that the various organs and cells in our body can use. This is the job of our digestive system. The digestive system acts in stages to digest our food digestive system the organs that have as their particular function the ingestion, digestion, and absorption of food or nutritive elements. They include the mouth, teeth, tongue, pharynx, esophagus, stomach, and intestines
Your body makes enzymes in the digestive system, including the mouth, stomach, and small intestine. The largest share is the work of the pancreas The digestive system ingests and digests food, absorbs released nutrients, and excretes food components that are indigestible. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation. These processes are regulated by neural and hormonal mechanisms This process is called digestion. It takes place in your digestive tract or gut, which is a long tube with muscly walls that runs from your mouth to your bottom (anus). Some parts of your digestive system mash up food physically, just like a food processor. Your mouth breaks food down into chunks The digestive system is made up of the digestive tract and other organs that help the body break down and absorb food. Your digestive tract is a long, twisting tube that starts at your mouth, and then involves your oesophagus, stomach, small intestine, large intestine and anus

. In the mouth, chewing breaks the food into smaller particles. Digestive enzymes in saliva are mixed with food before it passes down the esophagus into the reticulo-rumen (Figure 1) The digestive system provides receiving, mechanical and chemical processing of food, products absorption of splitting and removal of undigested residues. The organs of the digestive system include digestive channel through which food passes (mouth, esophagus, stomach, intestines) and digestive glands (salivary, pancreas, liver, etc.). The wall of the digestive tract consists of three layers. Introduction to the Digestive System. The digestive system includes the digestive tract and its accessory organs, which process food into molecules that can be absorbed and utilized by the cells of the body. Food is broken down, bit by bit, until the molecules are small enough to be absorbed and the waste products are eliminated. The digestive tract, also called the alimentary canal or.

The final step in digestion is the elimination of undigested food content and waste products. The undigested food material enters the colon, where most of the water is reabsorbed. Recall that the colon is also home to the microflora called intestinal flora that aid in the digestion process
How Your Digestive System Works. Your digestive system comprises the GI tract (or digestive tract), pancreas, liver and gallbladder. When your digestive system is in its normal rhythm, food and fluids pass from the stomach into the small intestine.
