Key Concepts

Ingestion

Ingestion is the process of taking food into the body through the mouth. It marks the beginning of the digestive process by physically consuming food, which is typically broken down into smaller pieces through chewing.

Digestion

Digestion involves the chemical and mechanical breakdown of food into its constituent nutrients. This process starts in the mouth and continues in the stomach and intestines, where enzymes and acids help to break down complex molecules.

Absorption

Absorption is the stage in which the digested nutrients pass through the walls of the digestive tract, especially the small intestine, into the bloodstream. This allows the body to transport nutrients to the cells for energy, growth, and repair.

Elimination

Elimination is the final process that removes indigestible substances and waste products from the body. It ensures that materials that cannot be absorbed or used by the body are expelled, typically through the large intestine and rectum.
