How does the circulatory system help the endocrine system complete its function?

1 Answer

Endocrine glands are ductless glands i.e they do not have any ducts and hence they release their secretions directly into the blood.

Explanation:

Secretions of endocrine glands are called hormones and hormones are released directly into the blood which is part of the circulatory system.
Hence, circulatory system helps the endocrine system in carrying the hormones released by the endocrine glands. i.e from the site of production to the site of action.
