Physiological mechanism
- 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). This process occurs across the mucosa of the intestine via the epithelial cells’ barrier that constitutes it.

What is the difference between adsorption and absorption?
Absorption can be defined as the process of assimilating substances across the intestinal epithelial cells or the tissues and organs through the process of active or passive transport. This can be facilitated through diffusion or osmosis and always follows the digestion process and never precedes it.
Absorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it. The energy of an acoustic, electromagnetic, or other wave is proportional to the square of its amplitude—i.e., the maximum displacement or movement of a point on the wave—and, as the wave.

Jul 15, 2021 · Absorption Definition and Examples. 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.
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. Read More. What Adsorption Means in Chemistry. By Anne Marie Helmenstine, Ph.D.

The process by which one substance, such as a solid or liquid, takes up another substance, such as a liquid or gas, through minute pores or spaces between its molecules. A paper towel takes up water, and water takes up carbon dioxide, by absorption. Chemistry. Compare adsorption.
Absorption happens when a wave loses energy as it transmits into a material. This can happen in a medium or at a boundary between two materials. When a wave is absorbed by a material, its energy turns into another form of energy, such as thermal or electrical energy.
