Arterial blocks... may be mobile (6)

I believe the answer is:

emboli

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

'arterial blocks' is the definition.
Although both the answer and definition are plural nouns, I can't see how they can define each other.

'may be mobile' is the wordplay.
'may be' indicates an anagram.
'mobile' anagrammed gives '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 Hindu.
