Here are the essential concepts you must grasp in order to answer the question correctly.
Endocrine System
The endocrine system is a network of glands that produce and release hormones, which help regulate various bodily functions such as metabolism, growth, and mood. It plays a crucial role in maintaining homeostasis, the body's stable internal environment, by responding to changes and signaling other organs to adjust their activities.

Homeostasis
Homeostasis refers to the process by which biological systems maintain a stable internal environment despite external changes. This involves various feedback mechanisms, including negative feedback, which counteracts deviations from a set point, ensuring that physiological parameters like temperature and pH remain within optimal ranges.

Feedback Mechanisms
Feedback mechanisms are processes that help regulate physiological functions in the body. Negative feedback reduces the output or activity of a system when a certain threshold is reached, while positive feedback amplifies responses, often leading to a specific outcome. Understanding these mechanisms is essential for grasping how the endocrine system maintains homeostasis.
