The Digestive System Structure and Functions Jermaine Kendrick Vista College 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). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are

The principal structure of the digestive system is an irregular tube‚ open at both ends‚ called the alimentary (al-i-MEN-tar-ee) canal or the gastrointestinal (GI) tract. In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building. Food must be broken down or digested and then absorbed through the walls of the digestive tube before it can actually enter the body and be used by cells The teeth

The digestive system is a group of organs that perform the process by which food‚ containing nutrients‚ is eaten and broken down into different components. This breakdown makes it possible for the digested material to pass through the intestinal wall into the blood stream. The digestive process contains many different steps that take place in many different organs.<br><br>The first step of digestion begins at the mouth‚ where the food enters the mouth. Saliva is secreted from the salivary glands

THE DIGESTIVE SYSTEM Functions of the Digestive System • Ingestion- where in food from outside of the body enters the alimentary tract through the mouth • Digestion- which could be mechanical (physical breakdown of food into smaller pieces or chemical (enzymatic action) • Absorption of digested materials into venous circulation as well as lymphatic capillaries • Provision of nutrients to the cells of the body • Elimination of undigested materials ANATOMY AND HISTOLOGY OF THE DIGESTIVE

The beef patties are protein‚and cheeseis a form of calcium‚ fat‚ and protein. The piece of the BIG MAC is placed in the mouth and chewed‚ the starch is being digested by saliva. The starch becomes a kind of sugar which is used as a nourishment for the cells. Saliva changes food to a form that can be used by the body called enzymes.

nutrients that the human body needs‚ in order to grow‚ repair‚ move‚ and maintain homeostasis. These nutrients are broken down and absorbed into the body at different rates‚ and into precise arrangements‚ as they travel through the organs throughout the digestive system. • Carbohydrates are the body’s preferred energy source‚ and are found in the forms of starch‚ sugar and fibre. Additionally‚ carbohydrates move into the small intestine‚ where enzymes released by the pancreas break those carbohydrates into
