Verified step by step guidance

1. Understand the role of the endocrine system: It is responsible for producing and releasing hormones, which are chemical messengers that regulate various functions in the body.
2. Recognize the function of the circulatory system: It transports blood throughout the body, delivering oxygen, nutrients, and hormones to cells and tissues.
3. Identify the relationship between the endocrine and circulatory systems: The circulatory system transports hormones produced by endocrine glands to their target organs and tissues, enabling them to exert their effects.
4. Clarify the misconception: The circulatory system does not store excess hormones for later use; hormones are typically broken down and excreted if not used.
5. Note the distinction: The circulatory system does not regulate hormone production nor produce hormones; these functions are specific to the endocrine glands themselves.
