What is the primary function of an organ system?

The primary function of an organ system is to consist of groups of organs working together to perform specific functions necessary for the survival and health of the organism. Each organ in the system plays a particular role within the larger context of the system, contributing to the overall function of the organism. For instance, the digestive system includes organs such as the stomach and intestines, which work collaboratively to break down food and absorb nutrients.

While digestion, regulation of bodily functions, and chemical reactions are important biological processes, they are specific activities that may occur within particular organ systems. For example, digestion is a function of the digestive system, but it is not the sole focus of the organ system as a whole. Instead, the definition of an organ system emphasizes the collaboration of multiple organs to achieve complex tasks, making the concept of groups of organs working together the most accurate representation of an organ system's primary function.
