Which term refers specifically to a buildup or collection in the bladder?

The term that refers specifically to a buildup or collection in the bladder is "Vesic/o." This prefix is derived from the Latin word "vesica," which means bladder. In medical terminology, "vesic/o" is commonly used in terms related to the bladder, including "vesiculitis," which refers to inflammation of the seminal vesicles, and "vesicoureteral," which pertains to the relationship between the bladder and the ureters.

The other terms have distinct meanings; "Viscer/o" relates to the internal organs or viscera, not specifically the bladder. "Vulv/o" pertains to the vulva, the external part of the female genitalia, and "Vestibul/o" refers to the vestibule, often used in context with the ear or the vestibule of the vagina. Therefore, the specificity of "Vesic/o" makes it the correct answer regarding the context of a buildup or collection in the bladder.
