An organ system is defined as a group of organs that collaborate to perform specific vital functions necessary for the survival and well-being of an organism. Each organ within the system has a distinct role, but they work in concert to achieve a common purpose. For instance, the digestive system includes organs such as the stomach, intestines, and liver, all of which contribute to the process of digestion and absorption of nutrients.

Understanding organ systems is critical as it illustrates how complex biological processes are organized within living organisms. This hierarchical organization—from cells to tissues to organs and then to organ systems—demonstrates the intricate interdependencies that sustain life. In summary, the ability of different organs to function together efficiently is what characterizes an organ system, making this answer the most accurate representation of the concept.
