In the human digestive system, the process of digestion has many stages, the first of which starts in the mouth (oral cavity). Digestion involves the breakdown of food into smaller and smaller components which can be absorbed and assimilated into the body.he organs known as the accessory digestive glands are the liver, gall bladder and pancreas. Other components include the mouth, teeth and epiglottis. The largest structure of the digestive system is the gastrointestinal tract (GI tract).
In Physiology, you will study the movement of food through the GI tract in detail. For now, it is important to understand a few basic principles and to relate them to the histological structure of the digestive system.he secretions of the associated glandular organs, such as the salivary glands, pancreas, liver, and gall bladder, aid the GI tract in accomplishing these functions. This laboratory will focus on the sequential segments of the gastrointestinal tract; the subsequent laboratory will focus on the glandular organs.
