An abnormal organic condition of the heart or of circulation.

• A. Aseptic Technique
• B. Heart Disease
• C. Antibody
• D. Bacteria

Answer: (B)

This item tests understanding of a medical term for disorders of the heart and circulation. The phrase “an abnormal organic condition of the heart or of circulation” defines heart disease, a broad label for any structural or functional problem affecting the heart or blood vessels. It encompasses a range of conditions—like those that impair pumping, blood flow, or heart rhythm—reflecting abnormalities in the heart or circulatory system. The other options refer to components of the immune system or a procedural practice (antibodies, bacteria, aseptic technique) and do not describe a heart- or circulation-related disease.
