In vivo意思

"In vivo" is a Latin term that means "within the living." It is used in various scientific contexts, particularly in biology and medicine, to indicate that experiments or observations are conducted inside a living organism, rather than in an artificial environment, such as a test tube or Petri dish.

In vivo studies are important in understanding how substances or processes affect living organisms in their natural state, including how they interact with the complex systems of the body. These studies can provide insights into the efficacy and safety of drugs, the effects of environmental factors on health, and the mechanisms of diseases, among other things.

In contrast, "in vitro" is another Latin term that means "within the glass" or "outside the living." It refers to experiments or observations that are conducted outside a living organism, typically in a laboratory setting using samples of tissue, cells, or molecules. In vitro studies are useful for controlling variables and for conducting preliminary research before in vivo experiments.
