What is a digestion easy definition?

What is digestion and example?
Digestion is defined as the process of absorbing food or ideas. An example of digestion is a person’s body turning carbohydrates into energy. An example of digestion is a student understanding a chapter they’ve read in a textbook.
What are the two types of digestion?
Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.
How do we digest food step by step?
There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food. The mechanical breakdown of food occurs via muscular contractions called peristalsis and segmentation.
How food is digested in our body?
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.

What are the 3 forms of digestion?
Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva.
What are the 3 methods of digestion?
The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.
