The primary roles of the digestive system are:
- breakdown of food into nutrients
- absorption of nutrients
- elimination of solid waste products
Digestion is the process of breaking down large food molecules into nutrients that the body can use
Absorption is the uptake and removal of nutrients from the digestive tract.
- The digestive tract is also called the gastrointestinal tract (GI), alimentary canal, or gut
