What role do hormones play in the human body?

• A. Regulating metabolism
• B. Providing physical support
• C. Facilitating movement
• D. Storing nutrients

Answer: (A)

Hormones play a critical role in regulating metabolism in the human body. They are chemical messengers produced by various glands within the endocrine system and are released into the bloodstream, where they travel to target tissues and organs to exert their effects. This regulation of metabolism involves the control of processes such as how the body uses energy, how it breaks down and builds up substances, and how it responds to changes in environmental conditions. For instance, hormones like insulin and glucagon play pivotal roles in managing blood sugar levels, while thyroid hormones are essential for regulating the basal metabolic rate. These hormonal signals ensure that energy production, storage, and expenditure are balanced according to the body's needs. In contrast, the other options—providing physical support, facilitating movement, and storing nutrients—are functions more associated with other systems in the body, such as the skeletal and muscular systems for support and movement, while various organs and tissues are responsible for nutrient storage. Thus, while hormones are involved in various physiological processes, their primary and essential role in the context of this question is the regulation of metabolism.
