Question:
Explanation:
Hormones are important for homeostasis. Together with the nervous system, they control most of the functions of the human body. Most hormones are regulated by feedback mechanisms. A feedback mechanism is a loop in which a product feeds back to control its own production. Most hormonal feedback mechanisms involve negative feedback loops. In negative feedback systems, a stimulus causes the release of a substance whose effects then inhibit its release. In this way, the concentration of hormones in the blood is kept within a narrow range.
Answer: we can conclude that the correct answer is:
Hormones.
