Which term describes the measurement of weight in medical terminology?

The term that describes the measurement of weight in medical terminology is "bar/o." In medical contexts, "baro-" is a prefix used to refer specifically to pressure or weight, derived from the Greek word "baros," meaning weight. This prefix is often utilized in terms related to both environmental pressure and weight measurements in various medical practices, such as in barometric pressure or baroreceptors that sense changes in pressure within the body.

While the other options may have their own significance in medical terminology, they do not relate directly to the measurement of weight. "Bas/o" pertains to base or bottom, "bi/o" refers to life or living organisms, and "auditory" relates to hearing. None of these options connect to the concept of weight measurement like "bar/o" does.
