Undissolved materials in the vascular system can be mobile (6)

I believe the answer is:

emboli

I'm a little stuck... Click here to teach me more about this clue!

'undissolved materials in the vascular system' is the definition.
I can't judge whether this defines the answer.

'can be mobile' is the wordplay.
'can be' indicates an anagram.
'mobile' is an anagram of 'EMBOLI'.

Can you help me to learn more?

(Another definition for emboli that I've seen is " Blood clots or air bubbles which cause arterial blockages".)

I've seen this clue in the Sydney Morning Herald.
