The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. Although the small intestine is the workhorse of the system, where the majority of digestion occurs, and where most of the released nutrients are absorbed into the blood or lymph, each of the digestive system organs makes a vital contribution to this process. Esophagus. The digestive system. The digestive system. The first function of the digestive system is ingestion, or the intake of food. The time required for food passage through the digestive tract ranges from 1 to 3 days depending upon characteristics of the food and the specific nutritient involved. The time required for food passage through the digestive tract ranges from 1 to 3 days depending upon characteristics of the food and the specific nutritient involved. For a long time, researchers suggested that hormones have receptors just in the peripheral tissues and do not gain access to the central nervous system (CNS) (Lupien and Lepage, 2001[]).However, observations have demonstrated the effect of anti-inflammatory drugs (which are considered synthetic hormones) on behavioral and cognitive disorders … In the mouth, chewing breaks the food into smaller particles. The digestive system is made up of the digestive tract and other organs that help the body break down and absorb food. The long continuous tube that is the digestive tract is about 9 meters in length. Digestive system helps in breaking complex food into simpler forms. A number of secretions and the activity of a variety of enzymes, starting from the mouth till the intestines, are involved in this process. The long continuous tube that is the digestive tract is about 9 meters in length. Helping them along the way are the pancreas, gall bladder and liver. The ENS controls secretions, blood flow, hormone release, and motility (the movement of food through the digestive tract), all of which are part of the digestive process. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The digestive system has a complex system of food movement and secretion regulation, which are vital for its proper function.
