Function. The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.

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.

What are the functions of the digestive system? Its converts food into small molecules that can be used by the cells of the body. Food is processed by the digestive system in four places-ingestion, digestion, absorption, and elimination.

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 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.

The function of the digestive system is to break down the foods you eat, release their nutrients, and absorb those nutrients into the body.

Description of the digestive system Digestion begins with the mouth. Even the smell of food can generate saliva, which is secreted by the salivary glands in the mouth, contains an enzyme, salivary amylase, which breaks down starch. Teeth, which are part of the skeletal system, play a key role in digestion.

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.

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 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 breakdown of the nutrients requires the coordination of several enzymes secreted from specialized cells within the mouth, stomach, intestines, and liver. The major organs or structures that coordinate digestion within the human body include the mouth, esophagus, stomach, small and large intestines, and liver.

Functions are digestion and absorption. Completed in the small intestine. Presence of chyme in the duodenum stimulates enzyme production in the small intestine. Accessory organs such as liver, pancreas and gallbladder also produce digestive enzymes.

Functions The two main functions of the gastrointestinal mucosa are concerned with digestion and absorption of dietary nutrients and as a defence against many noxious dietary sub- stances and bacteria. The digestive mechanisms of the gut reside at two levels.

From the above differences, we can conclude that both small intestine and large intestine play a major role in digestion. Small intestines are involved in the digestion of food and absorption of nutrients. The large intestine is involved in the absorption of water and in the production of vitamins.

The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.

Two important functions of the digestive system are digestion and absorption. The nutrients that come from food are derived from proteins, fats, carbohydrates, vitamins, and minerals. These complex macromolecules must be broken down and absorbed in the gastrointestinal (GI) tract.
