Morphology

vegetation = vegetate (opaque) = veget + ation

The medical sense 'abnormal growth on heart valves' is a specialized extension of 'growth' and is unlikely to be derived by an average learner from the common meaning.

Etymology

Vegetation is also used in medicine because some abnormal tissue growths look a little like small plants, and the name comes from Latin vegetare 'to make lively'. So a medical 'vegetation' is a plant-like growth found on tissue or a heart valve.
