Sense: noun/1
Vivisection is the narrowest of these terms, referring specifically to cutting into or operating on a living animal for research. 'Animal testing' is the broadest, everyday term that covers any experimental procedure — from feeding chemicals to behavioural trials. 'Animal experimentation' sits between them in formality; it is preferred in academic and policy writing but carries the same wide scope as 'animal testing'. 'Dissection' is often confused with vivisection but is distinct: dissection usually means cutting open a dead specimen (e.g., a frog preserved in formaldehyde) to study anatomy, not performing experiments on a living creature. For example, a medical student might dissect a cadaver to learn organ placement, whereas a researcher performing a vivisection would operate on an anaesthetised live animal to observe how its heart responds to a new drug.

Etymology
Vivisection comes from Latin 'vivus' meaning 'alive' or 'living', combined with 'sectio' meaning 'a cutting'. The term entered English in the early 1700s as a precise label for the practice of cutting into live animals — as distinct from dissecting dead ones — for physiological investigation.
