Digestion helps food break down into nutrients, which the body uses for energy, growth, and cell repair. The nutrients are broken down into carbohydrates, proteins, fats, and vitamins. The organs that break down the food are the mouth, esophagus, stomach, small intestine, pancreas, and liver. The digestion process is controlled with hormone and nerve regulators. Nutrients are broken down into four different things. They are broken down into carbohydrates, proteins, fats, and vitamins. Carbohydrates are the sugars starches, and fiber found in most foods. Protein is found in meats and beans. Fat is found in oils, butter, and snack foods. There are different types of vitamins like B, C, A, D, E, and K.
Organs play an important role in the digestive system. The mouth chews the food and uses saliva to break down the food. The esophagus swallows the food and also uses saliva. The stomach relaxes the upper muscles in the stomach to let the food enter and the lower muscles mix the food with the stomach acid. The small intestine uses the peristalsis and digestive juices. The pancreas uses pancreatic juice. The liver uses bile acids to break down the food.
The digestive process is controlled by two regulators. The cells in the lining of the stomach and small intestine produce and release hormones that control the functions of the digestive systems. These hormones stimulate the production of the digestive juices and regulate appetite. There are two types of nerves that help control the action of the digestive
