Homeostasis

2. A dangerous condition caused by low sodium levels in the blood, often from over-hydration during endurance events.
7. The main component of blood plasma and sweat, crucial for preventing dehydration.
9. The mechanism that reverses a change to bring the body back to its set point.
12. A hormone released by the adrenal medulla to prepare the body for immediate activity.
13. The maintenance of a stable internal environment.
15. A dangerous rise in core body temperature when homeostatic mechanisms fail.
16. The process of maintaining core body temperature.

1. The narrowing of blood vessels to reduce heat loss.
2. The brain region acting as the body's thermostat.
3. Structures that detect a stimulus (like temperature or pressure).
4. A catabolic hormone released in response to long-term stress or exercise.
5. The process of breaking down food; often inhibited during intense exercise due to sympathetic activation.
6. The stored form of glucose in the liver and muscles, mobilized during exercise.
8. Fluid secreted by glands to cool the body through evaporation.
10. Muscles or glands that respond to carry out a response.
11. The widening of blood vessels near the skin to release heat.
14. All chemical reactions in the body that require homeostasis to function optimally.
