Answer:
system
Explanation:
An example of an organ system is the brain, spinal cord, and nerves working together.
<em>A system is a level of organization in living organisms in which body organs work together to perform similar functions. The organ system represents the highest level of body organization as opposed to organ, tissue, and cell level of organization.</em>
The cell is the smallest unit of organization of the body of living organisms. At the tissue level, cells aggregate together to perform similar functions while at the organ level, similar tissues come together to perform somewhat similar roles in the body of organisms.
<u>The brain, spinal cord, and nerves each represent an organ. When these work together in the body of organisms, the level of organization is described as organ systems or simply systems. </u>
