Which root means 'Blood clot'?

Which root means 'Blood clot'?

• A. Muscle
• B. Bone
• C. Blood clot
• D. Joint

Answer: (C)

Root meanings in medical terms carry the core idea of a word. The word part that means a blood clot comes from thrombos, giving the form thrombo- or thromb-. So the option that says “Blood clot” directly names that root, making it the best fit. This root appears in terms like thrombosis (clotting in a vessel) or thrombocyte (platelet), linking directly to clot concepts. Other options point to different parts of the body—muscle, bone, and joint—corresponding to roots like my/o, oste/o, and arthr/o, which do not relate to clotting.
