Examples
-

Compounds

Morphology
thromboplastin = thrombus (opaque) = thrombo + plasto + in
The laboratory reagent sense uses the same technical morphemes; the combining forms and '-in' are specialist elements not transparent to average learners.
Etymology
The word thromboplastin comes from the Greek parts thrombo- 'clot' and -plastin 'to form', and you can remember -plastin by thinking of plastic as 'shaping'. In the lab, a thromboplastin reagent is called that because it makes blood start to 'form' a 'clot', which is exactly what the test needs to measure.
