Hormones are associated with the circulatory system?

Yes, hormones are associated with the circulatory system. They are secreted by endocrine glands and released into the bloodstream, which then transports them to target organs or tissues in the body. Hormones regulate many physiological processes, including metabolism, growth and development, reproduction, and mood. The circulatory system is essential for the distribution of hormones throughout the body, allowing them to reach their target tissues and organs.
