Role of the Digestive system
Food is essential for our survival and is required for the chemical reactions that occur in every cell of the body
-foods we eat must be broken down physically and chemically into nutrients so that they can be absorbed by cell membranes.
This process is known as digestion, and the organs of the digestive system collectively perform these functions.
The digestive system consists of the digestive tract also called these two things

defecation
accessory organs of the digestive system, although food does not directly pass through them, their secretions play a vital role in processing food and nutrients!
