The Endocrine System Consists of Glands That

Question

The endocrine system consists of glands that
A) release chemicals into ducts
B) release chemicals carried by the blood
C) release chemicals into body cavities
D) all of the above

Accepted Answer

The endocrine system releases hormones directly into the bloodstream, which allows them to be transported throughout the body to target cells and organs. This differs from exocrine glands, which release chemicals into ducts to be carried to specific locations, such as sweat glands or salivary glands. Endocrine glands do not release chemicals into body cavities either.
