The term -lithiasis refers to which condition?

• A. movement
• B. inflammation
• C. condition of stones
• D. slipping

Answer: (C)

The term -lithiasis specifically denotes a condition characterized by the presence of stones (calculi) in the body, particularly within organs such as the kidneys, gallbladder, or bladder. The root "lith" originates from the Greek word "lithos," meaning stone, and the suffix "-iasis" signifies a pathological condition or disease. Thus, when combined, it indicates a state where stones form and may cause various symptoms or complications depending on their location and size. This term is commonly used in medical contexts to describe conditions such as nephrolithiasis (kidney stones) or cholelithiasis (gallstones), clearly illustrating its relevance in clinical practice.

Other options relate to different medical concepts: movement pertains to terms focused on mobility or motion, inflammation refers to the body's response to injury or infection characterized by redness, swelling, and heat, and slipping may refer to dislocations or similar incidents that do not relate to the presence of calculi or stones.
