The circulatory system is also known as which type of system?

• A. Nervous
• B. Organ
• C. Digestive
• D. Respiratory

Answer: (B)

Bodies organize their functions into organ systems, groups of organs that work together to perform broader tasks. The circulatory system isn’t a single organ; it coordinates the heart, blood vessels, and blood to move substances around the body. That collaborative nature is what defines it as an organ system. From the given options, the term that fits this concept best is Organ, since it points to a structure built from multiple parts that operate as a unit, rather than a single organ or a different system. The other choices describe distinct body systems themselves (nervous, digestive, respiratory) and wouldn’t describe the circulatory system.
