Question

Quizplus · Accepted Answer

The control of body fluid volume through processes such as drinking, urination, and the regulation of electrolyte levels is a classic example of negative feedback. Negative feedback loops work to maintain a stable internal environment by sensing changes and initiating responses that counteract or reverse those changes. In the case of body fluid control, this means that if the body detects an increase in fluid levels, it will trigger mechanisms to reduce fluid intake or increase urination to bring levels back to normal. Conversely, if fluid levels get too low, the body will initiate responses to increase fluid intake or decrease urination to restore balance.
