Digestion vs. Absorption: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 11, 2024
Digestion is the breakdown of food into smaller components, while absorption is the process of these components being taken into the body's bloodstream.

Key Differences

Digestion is the mechanical and chemical breakdown of food into smaller, soluble particles. In contrast, absorption refers to the process where the digestive system takes up nutrients from digested food into the bloodstream.

The process of digestion involves enzymes and stomach acids breaking down food. Absorption, on the other hand, occurs primarily in the intestines where nutrients pass through intestinal walls.

Digestion begins in the mouth and continues through the stomach and intestines. Absorption happens after digestion, mainly in the small intestine, where nutrients are absorbed.
