What does the Latin term in vivo mean?

"In vivo" is a Latin term used in scientific and medical contexts. It translates to "within the living" and refers to experiments, observations, or processes that are conducted within a living organism, typically an animal or a human subject. When research or testing is performed "in vivo," it means that it is being carried out within a living organism's natural biological system, rather than in a laboratory dish or simulated environment. This approach allows scientists to study the effects, behaviors, and responses of biological systems within their complex and dynamic contexts.
