IPA: /ˌɪntrəˈvaɪtəl/
KK: /ɪntrəˈvaɪtəl/
Relating to something that happens in or is done on a living organism.
The researchers used intravital techniques to observe the cells in real time.
Intravital is formed from "intra-" (meaning within) and "vital" (from Latin "vitalis", meaning of life). The word refers to something that occurs within the living body or during life.
Think of 'intra-' meaning 'within' and 'vital' relating to 'life' — this helps you remember that intravital refers to something that happens within life.
