What are the 4 process of digestion?
In the digestive process, there are four steps: intake, mechanical and chemical degradation of food, absorption of nutrients, and removal of indigestible food. Ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation are digestive processes.
What did you learn about digestive system?
What does your digestive system do? Your digestive system takes in food, breaks it down into the nutrients and energy your body needs, and then gets rid of the waste. Most of your digestive system is a long tube that runs from your mouth to your rectum. This “tube” includes your esophagus, stomach, and intestines.

| Esophagus | Peristalsis | None |

Mouth. The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.

How does food get digested?
As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
