Which of the following is NOT a function of the Circulatory System?

• A. Transport of waste
• B. Gas exchange
• C. Hormone secretion
• D. Transport of nutrients

Answer: (C)

The circulatory system plays several essential roles in maintaining homeostasis in the body. While it is responsible for the transport of waste, gas exchange, and the transport of nutrients, hormone secretion is not one of its primary functions. Instead, the circulatory system facilitates the movement of hormones through the bloodstream after they have been produced and secreted by endocrine glands. In this way, hormones travel to various target organs and tissues to exert their effects, but the actual production and secretion of hormones take place in other systems, particularly the endocrine system. Therefore, identifying hormone secretion as not a function of the circulatory system highlights the distinctive roles that various body systems play in overall physiology.
