The digestive system has three main functions: digestion of food, absorption of nutrients, and elimination of solid food waste. Digestion is the process of breaking down food into components the body can absorb. It consists of two types of processes: mechanical digestion and chemical digestion.

The salivary glands, liver and gall bladder, and the pancreas aid the processes of ingestion, digestion, and absorption. These accessory organs of digestion play key roles in the digestive process. Each of these organs either secretes or stores substances that pass through ducts into the alimentary canal.

The four most important parts of digestive system is the mouth, stomach, small intestine, and the large intestine. Mouth Food is taken into the body by the mouth. The teeth bite off little pieces of the food into the throat. The food goes down the throat, through the esophagus, and to the stomach.

Your body makes enzymes in the digestive system, including the mouth, stomach, and small intestine. The largest share is the work of the pancreas. Digestive enzymes help your body break down carbohydrates, fats, and proteins. This is necessary to allow for the absorption of nutrients and to maintain optimal health.

The digestive system is made up of a group of organs that work together to break down food. During digestion larger molecules are broken down into smaller ones. These molecules are transported around our body to be used for energy, growth and repair.

Overview. The human body uses the process of digestion to break down food into a form that can be absorbed and used for fuel. The organs of the digestive system are the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine and anus.

Functions of the duodenum The main tasks of the duodenum are: neutralization of the acidic gastric juice through production of alkaline secrets. mechanical processing and digestion of chyme. mixing bile and pancreatic enzymes.

To start, some definitions: Digestion refers to how the body processes food in the gastrointestinal (GI) tract and eliminates food waste via the intestines. Metabolism refers to how the cells utilize the energy we have absorbed from food during digestion.

Animals – The Digestive System. Digestion is the how the body breaks down food so it can be taken in and used. There are many organs in the digestive system each with a particular job to do. Other organs such as the liver and pancreas also play a role in digestion by producing chemicals that help to break down food.

There are three main functions of the gastrointestinal tract, including transportation, digestion, and absorption of food. The mucosal integrity of the gastrointestinal tract and the functioning of its accessory organs are vital in maintaining the health of your patient.

The digestive system is partitioned into many regions, each with a certain function. The digestive system consists of the pharynx, the esophagus, the crop, the intestine and the gizzard. Food such as soil enters the earthworm's mouth where it is swallowed by the pharynx.

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).

As in all vertebrates, the pancreas has two digestive functions. It is the source of: 1) exocrine secretion of digestive enzymes (proteases, lipases, and carbohydrases) into the intestine and 2) endocrine secretion of the hormones insulin and glucagon that act to lower and raise blood sugar.

The stomach's main function is digestion. It does this by: Storing the food we eat. Breaking down the food into a liquidy mixture called chyme.
