Crossword Genius

Circulation of family confused master (11)

Ross

I believe the answer is:

'circulation' is the definition.
(thesaurus)

'family confused master' is the wordplay.
'family' becomes 'blood' (I've seen this in other clues).
'confused' indicates an anagram.
'master' with letters rearranged gives 'stream'.
'blood'+'stream'='BLOODSTREAM'

'of' acts as a link.

(Other definitions for bloodstream that I've seen before include "It circulates in vessels", "current in vessels", "Vital channel", "vital passage", "something essential to human life".)
