The spelling of "autopsia in vivo" can be a bit confusing at first glance. The word "autopsia" refers to an examination of a deceased body, but when paired with "in vivo" (meaning "in the living"), it takes on a different meaning. The correct pronunciation of this term is [aw-top-see-ah in vee-voh], with the stress placed on the second syllable of "autopsia". The combination of the Greek and Latin roots used here results in a spelling that may be unfamiliar to some, but its meaning is crucial in the medical field.
Examination of the organs, especially the abdominal organs, during life by means of an exploratory incision.
