What term describes a group of organs working together to perform a function?

• A. A group of organs working together to perform a function.
• B. A single organ performing a function.
• C. A living thing.
• D. A group of cells.

Answer: (A)

The idea being tested is how different parts of the body cooperate to carry out a task, which is described by the term organ system. An organ system is a group of organs that work together to perform a common function, with each organ contributing a piece of the overall job—like digestion or circulation. This makes the option that states the concept of multiple organs collaborating to perform a function the best choice, because it captures the cooperative nature of coordination across organs rather than focusing on just one organ, the whole living thing, or merely cells. A single organ is only one structure, a living thing refers to the entire organism, and a group of cells describes tissue, not the integrated operation of multiple organs.
