Which list correctly names all 11 body systems?

• A. Skeletal, Muscular, Circulatory, Nervous
• B. Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Reproductive
• C. Respiratory, Digestive, Nervous, Endocrine
• D. Circulatory, Respiratory, Digestive, Nervous, Endocrine

Answer: (B)

The question tests your knowledge of the 11 body systems and their standard names. The correct list is the one that includes all of them: integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive. Each of these names corresponds to a distinct system with its own major organs and functions (for example, the integumentary system includes skin, hair, and nails; the cardiovascular system includes the heart and blood vessels; the lymphatic system is tied to immunity and fluid return).

The other options only name a subset of systems, so they don’t provide a complete set. They omit several major body systems, which is why they’re not correct choices for listing all 11.
