HUMAN DIGESTIVE SYSTEM

The human digestive system breaks down food into nutrients the body can use, then eliminates waste. It consists of the gastrointestinal (GI) tract (mouth, esophagus, stomach, small intestine, large intestine, rectum, anus) and accessory organs (salivary glands, liver, gallbladder, pancreas). Food moves through the GI tract, where enzymes and acids break it down, and nutrients are absorbed. The liver produces bile to help digest fats, and the pancreas provides digestive juices. Finally, waste is expelled.

 Parts of the Digestive System include the Gastrointestinal Tract which is   a long, hollow tube that food travels through. Themouth where digestion begins. The Esophagus which  is  a tube that transports food from the mouth to the stomach. The Stomach which is a  muscular organ that churns food and uses acid to further break it down. The  Small IntestineThe longest part of the GI tract, where most nutrient absorption takes place. The Large Intestine that  Absorbs water and electrolytes from indigestible food matter. The Rectum and Anus. The final parts of the digestive tract, where waste is stored and eliminated. 

 

Other parts are the accessory organs  which are Organs that aid digestion by producing substances like enzymes and bile. The Salivary Glands produce saliva, which moistens food and contains enzymes for carbohydrate digestion. The Liver that produces bile, which is crucial for fat digestion, and processes absorbed nutrients. The Gallbladder that stores and concentrates bile made by the liver. 

And the Pancreas that releases enzymes that break down carbohydrates, proteins, and fats, as well as hormones that regulate blood sugar.
