Didestive System in Human

Didestive System in Human (SUMMARY)


 Digestive system consists of the oral cavity, pharynx, esophagus, stomach, small intestine, and colon, liver, and pancreas. In the oral cavity are the teeth, tongue and salivary glands. Teeth useful for chewing food mechanically. Tongue putting food to be chewed and pushed the food in. into the esophagus. Saliva wrap food with digestive enzymes.Esophagus is the channel that connects the mouth to the stomach. Food pushed into in the stomach by peristalsis. Food into the stomach, then mixed with the sap of the stomach and removed to the small intestine. Three important substances produced in the stomach lining, namely hydrochloric acid, pepsin, and renin. The small intestine consists of three parts, the duodenum, the intestine is empty, and intestinal absorption. Sari-sari absorption of food occurs in the small intestine and the water is absorbed in the colon. Residual food excreted through the anus. Carbohydrates are the source of energy. Protein as a replacement and growth, as well as enzyme components. Fat as a source of energy reserves that protect the body from low temperatures. Vitamins are useful to smooth the body's metabolism. Functioning water dissolves nutrients, accelerate the reaction in the body, regulate body temperature, and transporting the waste to a disposal tool. Mineral salts have a specific role in the body. Good food can meet the body's nutritional needs and balanced nutrients. Nutritional adequacy is influenced by several factors, such as age, growth period, sex, weight, and height, as well as body activity, genes, pregnant or lactating. Abnormalities of the digestive system, among others, parotitis, peptic ulcers, appendicitis, diarrhea, constipation, or constipation.
