target organs
The bloodstream. The way it works is that endocrine glands secrete hormones into the circulatory system. In that way they are carried throughout the body.
hormones are carried around the body in the blood
Hormones are chemcial messengers released into the blood stream to be carried through out the body to target cells.
Earthworms have a closed circulatory system. Blood is pumped throughout its body by ringed blood vessels. An open circulatory system is not contained in vessels. In a closed circulatory system oxygen is carried in blood! hope this helps=)
Hormones
The chemicals secreted by the endocrine system are known as hormones. These chemical messengers are carried by the circulatory system to their target tissues.
The endocrine system's messages are in the form of chemicals called hormones. They are carried through the body by the circulatory system.

Endocrine glands secrete chemical messengers called hormones. These chemicals are secreted directly into the bloodstream, where they are carried by the circulatory system to target tissues throughout the body.
Endocrine glands release chemicals directly into the bloodstream. These hormones are then carried by the circulatory system to their target tissues.
Hormones are carried in the blood
The message of endocrine glands consists of the chemical secretions known as hormones that are made by the endocrine system's ductless glands. Hormones are secreted into blood for their transportation to target organs, which are their specific site of action.
