Organs
Organs (/ˈɔːrɡənz/) are groups of tissues with similar functions. Plant and animal life relies on many organs that coexist in organ systems.[1]
Etymology
The word "organ" comes from the Old English organ, which is derived from the Latin organum, itself a borrowing from Greek ὄργανον (órganon), "organ, instrument, tool".[2]
