The endocrine system's function includes which of the following statements?

• A. Produce hormones
• B. Regulate body functions
• C. Regulate metabolic functions
• D. All of the above

Answer: (D)

The endocrine system operates through hormones acting as chemical messengers to coordinate activities throughout the body. Glands such as the pituitary, thyroid, adrenal, pancreas, and gonads produce these hormones, which travel in the bloodstream to target tissues. This system influences a wide range of body functions, including heart rate, fluid balance, growth, and reproductive processes, as well as metabolic processes like energy production, nutrient storage, and glucose regulation. Because producing hormones, regulating body functions, and regulating metabolic functions are all correct aspects of what the endocrine system does, the most complete choice is that all of the above.
