The Human Digestive The human digestive system functions to digest and absorb nutrients from the food consumed. The process begins in the mouth, food is chewed and mixed with saliva. After swallowing, food enters the esophagus to the stomach where it is digested mechanically and chemically by stomach acid. Then the food flows into the small intestine, namely the duodenum, jejunum and ileum, where most of the nutrients are absorbed. Leftover food enters the large intestine or colon, water and minerals are absorbed, then ends up in the rectum as feces or faeces before being excreted through the anus. Other important organs are the liver, pancreas and salivary glands which produce digestive juices. Blood cells, smooth muscles and nerves coordinate the digestive system. In this way, the digestive system ensures that nutrients from food can be absorbed and utilized by the body. To maintain the health of the digestive system, we are advised to eat balanced nutritious foods rich in fiber from fruits, vegetables and whole grains. Drinking enough water every day is also important to clean up leftovers. In addition, avoid excessively spicy and fatty foods that can trigger digestive problems. Regular exercise, regular bowel movements, and chewing food slowly also help the digestive system work smoothly. Reducing stress with meditation and getting enough rest is also necessary so that the digestive system is not disturbed by stress and fatigue. If symptoms such as stomach ache or bowel problems appear, consult a doctor immediately. By adopting a healthy lifestyle, the digestive system will remain fit and function optimally.
