Question

choose the term that has a root meaning blood vessel: multiple choice dorsal integument cardiovascular respiratory lymph

Explanation:

To solve this, we analyze each term:

• "dorsal" relates to the back (e.g., dorsal cavity), no blood vessel root.
• "integument" refers to the skin (integumentary system), no blood vessel root.
• "cardiovascular" breaks into "cardio-" (heart) and "vascul-" (vessel) + "-ar" (pertaining to). The root "vascul-" means blood vessel.
• "respiratory" relates to breathing (respiratory system), no blood vessel root.
• "lymph" relates to lymphatic system (lymph fluid/vessels, but the root of "lymph" itself doesn't mean blood vessel; "cardiovascular" has a direct vessel - related root).

Answer:

C. cardiovascular
