PY - 2017 T2 - The Big Picture: Histology AB - The digestive system consists of the gastrointestinal (GI) tract (or gut), which includes the oral cavity (mouth), esophagus, stomach, small intestine, and large intestine, and the accessory organs, which include the salivary glands, pancreas, liver, and gallbladder. The major function of the digestive system is to acquire nutrient molecules from ingested food and eliminate indigestible remnants. The digestive system also maintains a barrier between the contents of its lumen and body tissues and provides immune protection against infectious disease. The activities of the digestive system are regulated by the enteric nervous system and by both local and systemic hormones.
