The root ur/o refers to which bodily substance?

• A. Head
• B. Tissue
• C. Urine
• D. Gallbladder

Answer: (C)

ur/o is the combining form for urine, the liquid waste produced by the kidneys and excreted through the urinary tract. Terms built with this root relate to urine or the urinary system, such as urinalysis (a test of urine) or urology (the field dealing with urine and the urinary tract). The other options point to different structures—head, tissue, or gallbladder—and are not connected to this root.
