trocas

Trocas is the plural form of troca in Portuguese, and it designates an act of exchanging or swapping. The term is widely used across different contexts to describe the transfer of goods, services, information, or other properties between two or more parties, typically under agreed terms or understood conventions.

In economics and commerce, trocas refer to exchanges or trades between individuals, businesses, or organizations. This can include barter arrangements where goods or services are exchanged directly without money, as well as more formal exchanges of assets, commodities, or non-talable values. The concept also appears in discussions of market mechanisms, tradeoffs, and intermediation, where actors seek mutually beneficial swaps or reallocation of resources.

In the biological and physiological sense, trocas often appear in the phrase trocas gasosas, which describes the exchange of gases (such as oxygen and carbon dioxide) between an organism and its environment, typically occurring in respiratory surfaces like lungs or gills.

In everyday language and digital communication, trocas is used to describe the act of sharing or transferring information, messages, or experiences. Examples include trocas de mensagens, trocas de contatos ou trocas culturais entre pessoas or communities.

Related terms include troca (singular), permuta, intercâmbio and troca de dados. See also concepts of exchange theory, trade, and barter in economic or social contexts.
