What is the meaning of the root "Vas(o)"?

Bone
Blood vessel
Muscle
Nerve

The correct answer is: Blood vessel

The root "Vas(o)" is derived from the Latin word "vas" which means vessel or container. In medical terms, it is mainly used to refer to blood vessels, and therefore option B is the correct definition. Option A, bone, does not relate to the meaning of "vas(o)" and option C, muscle, is derived from the Greek root "myo" rather than "vas". Option D, nerve, is derived from the Latin word "nervus" and does not have a direct connection to "vas(o)". Therefore, option B is the most appropriate choice for the meaning of the root "Vas(o)".
