Groups of body organs acting together to perform one or more functions are called what?

Tissues
Systems
Structures
Organs

The correct answer is: Systems

The term used to describe groups of body organs working together to perform specific functions is "systems." In the human body, systems are composed of multiple organs that coordinate their activities to achieve a common goal. For example, the cardiovascular system includes the heart and blood vessels, working in unison to circulate blood throughout the body. Understanding this concept is important as it helps recognize the complexity and interdependence of bodily functions. While tissues are groups of similar cells that perform a similar function and organs are individual structures within the body, systems represent a higher level of organization, integrating various organs to support overall health and function. Structures, on the other hand, are more general and can refer to both organs and tissues, but they do not specifically imply a functional collaboration as systems do.
