Question

Which best explains how the body maintains homeostasis?

O All systems work together to stabilize the body.
O Each system works independently to stabilize the body.
O All systems work together to match the external environment.
O Each system works independently to match the external environment.

Answer 1

The body maintains homeostasis by all systems working together to stabilize the body. Basic bodily functions such as heart rate and breathing may be stimulated or slowed under neural control. The nervous system helps regulate breathing and the urinary and digestive systems, and it interacts with the endocrine system1.

Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them. For example, if your body temperature is too high, a negative feedback loop will act to bring it back down towards the set point, or target value, of 98.6°F / 37.0°C2.

So I believe your answer should be A.

I hope this helps!
