The digestive system is responsible for taking whole foods and turning them into energy and nutrients to allow the body to function, grow, and repair itself. The six primary processes of the digestive system include: Ingestion of food. Secretion of fluids and digestive enzymes.

What is the primary function of the digestive system? To break down and absorb nutrients, salts, and water, as well as to eliminate some wastes. What is digestion? Digestion is the process by which large complex molecules in food are broken down into smaller molecules that can be used by the body.

The digestive system has three main functions. They are digestion, absorption, and elimination. The digestive system starts at the mouth when food gets bitten into smaller and smaller pieces and is mixed with saliva. The teeth crush and grind the food.

The Digestive System runs from the mouth to the anus and includes the stomach, the large and small intestines and a number of accessory organs, including the salivary glands, liver, gallbladder and pancreas.

The main functions of the cecum are to absorb fluids and salts that remain after completion of intestinal digestion and absorption and to mix its contents with a lubricating substance, mucus. The internal wall of the cecum is composed of a thick mucous membrane, through which water and salts are absorbed.

', 'Mechanical digestion starts in the mouth, with the physical processing of food by the teeth, and continues in the stomach.']

['Their function is to increase the surface area of the small intestinal wall for absorption of the digested food.', 'These projections absorb the protein molecules and help in the transfer of the proteins to all cells and tissues.']

The digestive system consists of the parts of the body involved in chewing and digesting feed. This system also moves the digested feed through the animal's body and absorbs the products of digestion. Different species of animals are better able to digest certain types of feeds than others.

The main organs of the digestive system are the mouth, esophagus, stomach, small intestine, and large intestine. The liver, gallbladder, and pancreas contribute chemicals that aid in digestion.

Liver. The liver has many functions, but its main job within the digestive system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting fat and some vitamins.

There are three main functions of the gastrointestinal tract, including transportation, digestion, and absorption of food.

The final function of the digestive system is the excretion of waste in a process known as defecation. Defecation removes indigestible substances from the body so that they do not accumulate inside the gut.

It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large intestines.

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.

Chemical digestion in the small intestine relies on the activities of three accessory digestive organs: the liver, pancreas, and gallbladder (Figure 1). The digestive role of the liver is to produce bile and export it to the duodenum. The gallbladder primarily stores, concentrates, and releases bile.

The first function of the digestive system is ingestion, or the intake of food. The mouth is responsible for this function, as it is the orifice through which all food enters the body. The mouth and stomach are also responsible for the storage of food as it is waiting to be digested.
