  • Ingestion and Propulsion.
  • Digestion.
  • Absorption of Nutrients.
  • Egestion: Elimintating Wastes.

What are the 4 stages of processing food?

There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food.

How does the body process the food you eat?

The body processes the food you eat by breaking it down in to smaller particles, absorbing nutrients and getting rid of waste products. These processes occur in the digestive tract, a long tube that connects the the mouth and the anus.

Where do the four stages of food processing take place?

These processes occur in the digestive tract, a long tube that connects the the mouth and the anus. The four stages of food processing follow a chronological order in which the previous stage prepares the food for further processing during the following stage.

What is the process of breaking down food called?

Mechanical breakdown starts with mastication (chewing) in the mouth. Teeth crush and grind large food particles, while saliva initiates the chemical breakdown of food and enables its movement downward. The slippery mass of partially broken-down food is called bolus, which moves down the digestive tract as you swallow.
