Question

how does the body maintain homeostasis when its inner temperature becomes higher than the normal body temperature?
shivering
sweating
goosebumps

Explanation:

When the body's inner temperature is higher than normal, sweating helps cool the body. Sweat evaporates from the skin, taking heat away. Shivering generates heat (for when body is cold), and goosebumps (piloerection) trap a layer of air (more relevant in animals for insulation, less effective in humans for cooling).

Answer:

sweating
