Meaning of Absorption
What is Absorption:
The term absorption indicates the action of absorbing. However, it is used mainly to refer to the retention of a substance by the molecules that another has, either in a liquid or a gaseous state.
The word absorption can be used in various areas such as physics, chemistry, biology or economics, therefore, it can have different uses and meanings.
Absorption in physics
In physics, absorption indicates the loss of intensity of electromagnetic or sound wave radiation when it passes through a medium. Therefore, when reference is made to the absorption of sound waves, this indicates the existence of difficulties for the propagation of sound.
Absorption in chemistry
On the other hand, absorption in chemistry is a process that consists of the separation of one or more components of a gas using a liquid solvent that will create a solution.
Absorption in linguistics
In linguistics, absorption is the phenomenon in which the sound of a vowel disappears when it is incorporated into a consonant.
Absorption in economics
In the area of economics and business, absorption generally indicates the exposure of operations through which one or more companies dissolve to join an existing one or to acquire and start a new company.
For example, "A large shoe company absorbed my grandfather's small shoe factory, now its models are endorsed by a large industrial corporation."
Absorption in biology
In biology, absorption is a process that occurs during the digestion of food in living beings, in which a set of organs carry out a chemical and physical process in order to absorb the nutrients, minerals and external substances necessary to live.
These nutrients are then transported from the digestive system to the blood or lymph.
In the development of digestion, the body absorbs only those nutrients that the body needs for the proper functioning and development of activities in individuals or animals.
The walls of the small intestine are where most of the process of digestion and absorption of water, sugars, minerals and vitamins, as well as proteins, fats and hydrates takes place.
Once the necessary nutrients are absorbed, they are transported through the blood to those cells in which they are to be used.

Absorption and adsorption
Absorption and adsorption are chemical and physical processes that are part of what is called sorption and is characterized by adding or joining one substance to another. However, absorption and adsorption are two different processes.
Absorption is the phenomenon through which atoms, molecules or ions pass from a phase, either liquid or gaseous, to a liquid or gaseous one. That is, the matter is transferred from a phase A (absorbate) to another phase B (absorbent) in which it is dissolved or dispersed.
On the contrary, adsorption is a phenomenon in which a substance A (adsorbate) present in a liquid or gas, remains adhered to a solid substance B (adsorbent). In this case there is no mass transfer, a layer of the adsorbent is created on the adsorbate.
