I believe the answer is:

percolates

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

'strains' is the definition.
The answer and definition can be both related to bodily activities as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?

'carol pete's arranged' is the wordplay.
'arranged' indicates anagramming the letters (letters rearranged).
'carol'+'petes'='carolpetes'
'carolpetes' with letters rearranged gives 'PERCOLATES'.

'of' is the link.

Can you help me to learn more?
