Detailed explanation-1: -Digestion begins in the mouth. The food is ground up by the teeth and moistened with saliva to make it easy to swallow. Saliva also has a special chemical, called an enzyme, which starts breaking down carbohydrates into sugars.
Detailed explanation-2: -The organs of the digestive system are the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine and anus. Recognizing how these organs work together to digest food is key to understanding how digestion works.
Detailed explanation-3: -The teeth break food into small pieces. The lips and tongue position food so that you can chew. When food is in your mouth, salivary glands in your mouth release saliva, which softens the food and begins chemical digestion. The tongue pushes the food to the back of the mouth and down the throat while swallowing.
Detailed explanation-4: -Food enters the digestive system through the mouth. Food is broken down into smaller pieces by chewing. The teeth cut and crush the food, while it’s mixed with saliva. This process helps to make it soft and easier to swallow.
