Morphology
apheresis = a + pheresis
The medical sense is formed from the same Greek combining elements but functions as a technical borrowing (e.g., plasmapheresis), so its internal parts are not transparently meaningful to general learners.
Etymology
Apheresis comes from Greek parts a- 'away' and phairein 'to take', so it literally means 'taking away'. In medicine it is a procedure that 'takes away' part of a person's blood and returns the rest, which is why the word fits the treatment.
