Võõrorganismide

Võõrorganismide is the Estonian term for alien organisms or xenobiotics. In a biological context, it refers to organisms that are not native to a particular ecosystem or environment. These can include invasive species that disrupt local flora and fauna, or organisms introduced intentionally or unintentionally by humans. The study of võõrorganismide often involves understanding their ecological impact, their potential to outcompete native species, and the mechanisms of their spread. This can range from plants and animals to microorganisms.

In a broader sense, the term võõrorganismide can also extend to substances or compounds foreign to a biological system. For instance, in medicine and toxicology, it refers to exogenous substances that are introduced into the body and may have physiological effects, such as drugs, pollutants, or toxins. The body's response to these võõrorganismide involves various defense and metabolic pathways aimed at eliminating or detoxifying them. The interaction between an organism and võõrorganismide is a key area of research in ecology, conservation, and pharmacology.
