Absorption (biology)
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intest ...

Absorption (small intestine)
The small intestine or small bowel is an organ in the gastrointestinal tract where most of the absorption of nutrients from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pa ...

Absorption (chemistry)
In chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – liquid or solid material. This is a different process from adsorption, since molecules undergoing absorption a ...
, diffusion of particles of gas or liquid into liquid or solid materials

Absorption (skin)
Skin 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. Absorption ...

Absorption (pharmacology)
Absorption is the journey of a drug travelling from the site of administration to the site of action.
The drug travels by some route of administration (oral, topical-dermal, etc.) in a chosen dosage form (e.g., tablets, capsules, or in solut ...
, absorption of drugs into the body

Absorption (acoustics)
Acoustic absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. Part of the absorbed energy is transformed into heat and part is tran ...
, absorption of sound waves by a material
*
Absorption (electromagnetic radiation)
In physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon's energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy). ...
, absorption of light or other electromagnetic radiation by a material
*Absorption air conditioning, a type of
solar air conditioning
Solar air conditioning, or "solar-powered air conditioning", refers to any air conditioning (cooling) system that uses solar power.
This can be done through passive solar design, solar thermal energy conversion, and photovoltaic conversion (sunli ...

Absorption refrigerator
An absorption refrigerator is a refrigerator that uses a heat source (e.g., solar energy, a fossil-fueled flame, waste heat from factories, or district heating systems) to provide the energy needed to drive the cooling process. The system uses tw ...
, a refrigerator that runs on surplus heat rather than electricity
*
Dielectric absorption Dielectric absorption is the name given to the effect by which a capacitor, that has been charged for a long time, discharges only incompletely when briefly discharged. Although an ideal capacitor would remain at zero volts after being discharged, r ...
, the inability of a charged capacitor to completely discharge when briefly discharged
Mathematics and economics

Absorption (economics) In economics, 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. As the absorption is equal to the sum of all domest ...
, the total demand of an economy for goods and services both from within and without

Absorption (logic)
Absorption is a Validity (logic), valid argument form and rule of inference of propositional logic. The rule states that if P implies Q, then P implies P and Q. The rule makes it possible to introduce Logical conjunction, conjunctions to formal p ...

Absorption costing
Total absorption costing (TAC) is a method of Accounting cost which entails the full cost of manufacturing or providing a service. TAC includes not just the costs of materials and labour, but also of all manufacturing overheads (whether ‘fixed ...
, or total absorption costing, a method for appraising or valuing a firm's total inventory by including all the manufacturing costs incurred to produce those goods

Absorbing element In mathematics, an absorbing element (or annihilating element) is a special type of element of a set with respect to a binary operation on that set. The result of combining an absorbing element with any element of the set is the absorbing element i ...
, in mathematics, an element that does not change when it is combined in a binary operation with some other element

Absorption law
In algebra, the absorption law or absorption identity is an identity linking a pair of binary operations.
Two binary operations, ¤ and ⁂, are said to be connected by the absorption law if:
:''a'' ¤ (''a'' ⁂ ''b'') = ''a'' ⁂ (''a'' ¤ ''b ...

Adsorption
Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the ''adsorbate'' on the surface of the ''adsorbent''. This process differs from absorption, in which a f ...
