Which term means pertaining to the atria and the ventricles?

• A. Arthrography
• B. Astrocyte
• C. Atrioventricular
• D. Arthroscopy

Answer: (C)

The main idea here is recognizing how combining forms name parts of the heart and how the suffix signals relation. Atrioventricular is formed from atri/o (atrium) and ventricul/o (ventricle) with the adjective ending -ar, meaning pertaining to. This term describes structures that involve both heart chambers, such as the atrioventricular valves that sit between the atria and ventricles and regulate blood flow, and other aspects that connect or relate the two chambers. The other terms refer to joints or brain tissue—arthrography images a joint, astrocyte is a brain cell, and arthroscopy is a procedure to view inside a joint—so they don’t describe the heart’s atria and ventricles.
