It is called “obstruction” to the obstruction, with certain objects, of a road or path of small dimensions. The use of this can be both concrete (referring to cases of, for example, stagnation in road arteries or organs of the human body), as well as a metaphor to talk about the impediments imposed to carry out an activity (obstruction of justice). The term comes from the Latin word “obstructionis”; It is made up of the prefix “ob-“, which translates as “against”, in addition to “struere” (to gather or pile up) and “-ción”, used to give it the definition of “action and effect”. There is also talk of obstructionism, a political practice that aims to prevent the making of certain decisions, such as the approval of a law.

In medicine, it is called an “obstruction” when a biological material blocks organs that are tubular in shape, such as the intestine, or that need, in some way, the entry of oxygen, such as the nose and lungs. In the case of intestinal obstructions, these are caused by the presence of certain medical conditions, such as peritoneal carcinomatosis or superior mesenteric artery syndrome; Similarly, its origin can be found in mistakes made during abdominal surgeries. Pulmonary obstructions, likewise, are due to the combination of a series of diseases at the pulmonary level, which cause obstruction of the pathways through which the air reaches the organ.

Parliamentary obstruction, meanwhile, talks about the measures taken by the people who make up the body, after a certain law or project is rejected or whose approval is delayed. This is also known as filibustering, a technique popularized in Ancient Greece by Cato the Younger.
