Final answer:
Thrombolysis is the word that means the loosening of a blood clot.
Step-by-step explanation:
The word that means the loosening of a blood clot and can be built using the root word thromb/o is thrombolysis.
Thrombolysis refers to the process of breaking down a blood clot. It is often achieved through the use of thrombolytic drugs, which help to dissolve the clot and restore blood flow. This can be an important treatment option for conditions such as deep vein thrombosis or pulmonary embolism.
For example, if a blood clot forms in a blood vessel, it can hinder the flow of blood and potentially lead to serious health issues. Thrombolysis can help to remove the clot and promote the return of normal blood flow.
