Morphology

vasoconstriction = constriction (semi-transparent) = vaso + constriction

Formally composed of the combining form 'vaso-' (vessel) + 'constriction'; transparent to learners familiar with medical terms but the combining form is technical and may be unknown to average learners.

Etymology

Vasoconstriction comes from vaso- meaning 'vessel' and constrict meaning 'to make tight', the same idea you see in the common word string. So, vasoconstriction is when blood vessels become narrower or tighter and reduce blood flow.
