digestive system include the oral cavity (mouth)‚ esophagus‚ stomach‚ small and large intestine and rectum. Their role is to break down food and deliver the products to the blood for dispersal to the body cells. The undigested food that remains in the tract leaves the body through the anus as feces. The break down activities that begin in the mouth are completed in the small intestine. From that point on‚ the major function of the digestive system is to reclaim water. The liver is considered to be a digestive

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue‚ salivary glands‚ pancreas‚ liver‚ and gallbladder).[1] In this system‚ the process of digestion has many stages‚ the first of which starts in the mouth. Digestion involves the breakdown of food into smaller and smaller components‚ until they can be absorbed and assimilated into the body. Chewing‚ in which food is mixed with saliva begins the process of digestion. This produces a bolus

a series of hollow organs working together extending from the mouth to the anus. These hollow organs are the mouth‚ pharynx‚ esophagus‚ stomach‚ small intestine‚ large intestine‚ rectum‚ and anus. These hollow organs make up the gastrointestinal (GI) tract. The GI tract is aided by four accessory organs‚ the salivary glands‚ liver‚ gallbladder‚ and pancreas. (Johnson) There are five basic processes of the digestive system. These processes are motility‚ secretion‚ digestion‚ absorption‚ and excretion
