What is the function of the endocrine system?

• A. Regulate body temperature
• B. Control voluntary muscles
• C. Chemically regulate the body's functions
• D. Digestive enzyme production

Answer: (C)

The function of the endocrine system is to regulate the body's activities chemically, using hormones as messengers that travel through the bloodstream to target organs. These hormones coordinate processes such as metabolism, growth and development, reproduction, and responses to stress, helping keep the body's internal environment stable. For example, insulin helps control blood glucose levels, thyroid hormones adjust how fast the body uses energy, and adrenaline prepares the body for rapid action in a stressful situation. Digestive enzyme production is mainly an exocrine function, with glands releasing enzymes into the digestive tract rather than hormones into the bloodstream. Controlling voluntary muscles is handled by the somatic (voluntary) nervous system, and while hormones can influence temperature regulation indirectly, the primary control of temperature comes from nervous system mechanisms.
