Injuries to living tissue (6)
I believe the answer is:
wounds
'injuries to living tissue' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for wounds that I've seen before include "Injuries to bodies or feelings" , "wings" , "Inflicts damage to body or feelings" , "Inflicts injury on, physical or mental" , "Lesions, injuries" .)
