Homeostasis is maintained by which of the following organ systems in humans?
a_sh-v [17]

A. Multiple organ systems working together

Explanation:

When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.
