- Absorption occurs when ions, atoms, or molecules pass into a bulky material. These particles (the absorbate) diffuse or dissolve into the absorbent substance. A familiar example is a paper towel picking up water. Eventually, water evenly permeates the paper.

Absorption Definition. Absorption is a physiological mechanism by which simpler forms of molecules (both macromolecules and micromolecules) are transmitted (absorbed/assimilated) from the intestinal lumen to the circulatory system (blood or lymphatic).

Absorption is the movement of digested food molecules from the digestive system into the blood (glucose and amino acids) and lymph (fatty acids and glycerol) Nutrients are absorbed in the small intestine. Absorption can occur by diffusion, osmosis and active transport.
Jul 3, 2019 · Definition: Absorption is the process by which atoms, molecules, or ions enter a bulk phase (liquid, gas, solid). Absorption differs from from adsorption, since the atoms/molecules/ions are taken up by the volume, not by surface. Examples: absorption of carbon dioxide by sodium hydroxide.
