Question

The mixes saliva with the food during chewing.

Answer 1

Nutrition permits us to take in and use food substances that the body converts to energy and body structure. The digestive system includes all the organs and glands involved in this process of eating and digesting. Starting in the mouth, a long muscular tube provides continual fluid and vital nutrients. The coiled intestines alone are about 24 feet long. After we consume food, the body mechanically and chemically breaks it down, then transports it for absorption and defecation (final waste removal). The digestive glands (salivary glands, pancreas, liver, and gallbladder) produce or store secretions that the body carries to the digestive tract in ducts and breaks down chemically. Hope this will help you understand
