Absorption

• (chemistry) a process in which one substance permeates another; a fluid permeates or is dissolved by a liquid or solid
• (physics) the process in which incident radiated energy is retained without reflection or transmission on passing through a medium; "the absorption of photons by atoms or molecules"
• assimilation: the social process of absorbing one cultural group into harmony with another
• assimilation: the process of absorbing nutrients into the body after digestion
• concentration: complete attention; intense mental effort
• preoccupation: the mental state of being preoccupied by something
• Absorption is a route by which substances can enter the body through the skin. Along with inhalation, ingestion and injection, dermal absorption is a route of exposure for toxic substances and route of administration for medication.
• Digestion is the process of metabolism where by a biological entity processes a substance in order to chemically and mechanically convert the substance for the body to use.
• Absorption refers to the absorption of sound waves by a material. The absorption is the "missing piece", when comparing the total reflected and transmitted energy with the incident energy.
• Absorption is the total demand for all final marketed goods and services by all economic agents resident in an economy, regardless of the origin of the goods and services themselves.
• In pharmacology (and more specifically pharmacokinetics), absorption is the movement of a drug into the bloodstream.
• In physics, absorption is the process by which the energy of a photon is taken up by another entity, for example, by an atom whose valence electrons make transition between two electronic energy levels. The photon is destroyed in the process.
• The process in which incident radiant energy is retained by a substance by conversion to some other form of energy.
• the penetration of atoms, ions, or molecules into the bulk mass of a substance.
• In acoustics, the energy of sound waves being taken in (entering) the surface of any material rather than being bounced off or reflected. Materials are rated in terms of their ability to absorb sounds.
• Process in which digested food is absorbed by the lower part of the small intestine into the bloodstream.
• Acceptance by the carrier of a portion of a joint rate or charge which is less than the amount which it would receive for the service in the absence of such joint rate or charge.
• The process of an agent being taken into the vegetation, skin, materiel, or soil. Important for only a few agents.
• The allocation of specific pools or groups of fixed costs to associated units of production by a predetermined percentage or dollar amount, based on unit cost, machine or labor hours, or other factors.
