According to the context in which the term is used extraction may refer various questions. It is widely used in contexts such as chemistry, social origin, mining, dentistry, clinical analysis, mathematics, and computer science.
Take out something that is immersed in something else
In its broadest sense, extraction refers to act of removing something that is sunk, immersed or buried in something else or place. "Next week I have a turn at the dentist to perform the extraction of a wisdom tooth that is hurting me."
Use in mathematics
On the other hand, to instances of mathematics , the extraction is designated as inquiry that is carried out from the root of a certain quantity. "During this term, students will learn to extract cube roots."
Lineage of a person
Also, the word extraction is regularly used to refer to the origin or lineage that a person has. "Juan comes from a very low social background."
Chemical procedure that allows a substance to be separated to be dissolved
For the Chemistry, the extraction is that procedure in which a substance that can be dissolved in two solvents that is not miscible between them is separated, with different degree of solubility and that are in relation through an interface. The ratio of the concentrations that this substance presents at a certain temperature, in each of these solvents, will be constant. This same one is designated with the name of coefficient of distribution.
The steps would be as follows: the substance already dissolved in the solvent from which the extraction is proposed is placed inside the funnel, then, it is completed with the solvent in which it is extracted and in which the solubility of the substance is greater; the funnel is closed and it begins to stir to form an emulsion of two immiscible liquids and allow the dissolved substance between them to be distributed; the funnel valve must be opened to allow the contained gases to escape to the outside; let it rest for the interface to conform; open the lower tap of the funnel and let the thicker liquid run through.
Mining: procedure by which substances and materials are obtained
For its part, at the request of mining, extraction turns out to be one of the most common procedures when it comes to obtaining materials such as copper or oil, from deposits or mines in which they are buried in large quantities. The method requires a technique and the use of specialized machinery to be able to extract these materials.
Dentistry: surgery that removes a tooth
In dentistry, tooth extraction is a very common practice, formally known as extraction, and which basically consists of carrying out a surgery by which a tooth is extracted from the patient, using techniques and a specially prepared apparatus for it. The mission is to perform this surgery causing the least possible trauma to the patient. Being a very complex surgery requires expertise on the part of the dentist who practices it.
Since certainly remote times, tooth extraction has been practiced, obviously with a very large degree of rusticity in initiation times since not only did the materials and techniques of today not exist but also because anesthesia was not what it is today and then it caused tremendous pain to the patients. And not to mention the health consequences of the practice when it was done in a very elementary way.
The extraction of a tooth can be indicated by various pathologies, from a cavity to a tumor in a tooth. Now, the most important thing is that the diagnosis supports it and is carried out by a suitable professional.
Informatics: retrieve information
In computing, the extraction action is common and consists of retrieving structured information from documents through a computer.
Blood Collection: Diagnostic Medical Procedure
And finally, the concept is widely used at the behest of medicine to refer to a very common medical procedure that is requested from us to diagnose some ailment or disease. Blood extraction consists of inserting a fine needle into the arm, over an artery or vein, and collecting blood through it in a vial.
