What is a system in the context of the human body?

1. A type of tissue

2. A single organ

3. A group of organs that perform one or more vital functions for the body

4. A type of cell

The correct answer is: A group of organs that perform one or more vital functions for the body

The correct answer identifies a system in the context of the human body as a group of organs working together to perform one or more vital functions. Each organ within a system has a specific role that contributes to the body’s overall functioning. For example, the digestive system encompasses organs like the stomach and intestines, all of which collaborate to break down food, absorb nutrients, and eliminate waste. This interconnectedness is essential for maintaining homeostasis and supporting overall health. In contrast, the other options refer to different aspects of biological organization. Tissue describes a group of similar cells that perform a specific function, while a single organ, like the heart or lungs, can function independently but does not encompass the collaborative nature of systems. A type of cell refers to the most basic structural unit of life, which contributes to tissues but does not represent the higher-level organization seen in systems. Hence, the definition of a system as a collective of organs working in concert best captures the complexity and functionality required for survival in the human body.
