Final answer:
An 'embolectomy' is the medical term for the removal of an embolus, which is an obstruction in the bloodstream that can cause serious emergencies like heart attacks or strokes.
Step-by-step explanation:
The term constructed using embol/o to denote the excision or removal of an embolus is embolectomy. An embolus is a traveling obstruction in the bloodstream, such as a blood clot, air bubble, or other material, that can lead to a blockage in a vessel feeding a major organ, causing medical emergencies like a heart attack, stroke, or pulmonary embolism. The procedure of embolectomy is thus critical in restoring normal blood flow and preventing the severe consequences of an embolism.
