What is the term for a collection of organs that work together to perform broad physiological tasks?

• A. Organ
• B. Organ System
• C. Tissue
• D. Cell

Answer: (B)

Think of the body organized in levels where groups of organs come together to handle wide-ranging bodily tasks. An organ system is a collection of multiple organs that coordinate to perform broad physiological functions, such as circulating blood, exchanging gases, or digesting food. Each organ contributes a specialized role, but it’s their collaboration that enables large-scale processes and homeostasis. For example, the circulatory system includes the heart, blood vessels, and blood working together to move oxygen and nutrients throughout the body. In contrast, an organ is a single structure made of different tissues (like the heart itself), a tissue is a group of similar cells, and a cell is the basic unit of life. So the term for a collection of organs that work together to perform broad physiological tasks is organ system.
