In microbiology, in vivo is often used to refer to experimentation done in a whole organism, rather than in live isolated cells, for example, cultured cells derived from biopsies. In this situation, the more specific term is ex vivo. Once cells are disrupted and individual parts are tested or analyzed, this is known as in vitro. [citation needed]
in vivo: in life/in a living thing: An experiment or process performed on a living specimen. in vivo veritas: in a living thing [there is] truth: An expression used by biologists to express the fact that laboratory findings from testing an organism in vitro are not always reflected when applied to an organism in vivo. A pun on in vino veritas.
In vino veritas is a Latin phrase that means 'in wine, there is truth', suggesting a person under the influence of alcohol is more likely to speak their hidden thoughts and desires.

For example, microorganisms or cells can be studied in artificial culture ...

Livestreaming, live-streaming, or live streaming is the streaming of video or audio in real time or near real time. While often referred to simply as streaming, the real time nature of livestreaming differentiates it from other forms of streamed media, such as video-on-demand, vlogs, and YouTube videos. Livestreaming services encompass a wide ...

To compensate for this problem, in vivo experimentation allowed testing to occur in the original organism or environment. To bridge the dichotomy of benefits associated with both methodologies, in situ experimentation allowed the controlled aspects of in vitro to become coalesced with the natural environmental compositions of in vivo ...
