Hormones travel from endocrine glands through bloodstream to target organs.
the other name for endocrine glands is DUCTLESSglands.these are also called as so bec they wont contain special ducts to carry their secretions to target organs.while exocrine glands such as pancreas except langerhans are ducted gland as they release these hormones into their ducts.so for endocrine glands BLOOD acts as a carrier organ for transfer of these hormones to target sites.hence these glands called as a ductless glands....

By glands. Hormones are produced only by the endocrine glands, e.g., the pituitary, the adrenals, etc.. Hormones are "chemical messengers": they are sent by the glands to target organs and stimulate them to produce specific effects, e.g. the hormone thyroxin is manufactured by the thyroid gland to regulate the metabolism.
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.

Thyroid glands
Paracrine glands are similar to endocrine glands but instead of secreting material into the bloodstream or into their ducts, their products act on the target cells by diffusion of their material into the extracelular space or in the immediately subjacent connective tissue.
Endocrine glands release chemicals directly into the bloodstream. These hormones are then carried by the circulatory system to their target tissues.
The names of the hormones that target other endocrine glands stimulate their secretions are tropic hormones. Most, if not all, tropic hormones come from the hypothalamus or anterior pituitary gland.

the target cells have receptor proteins for the signals released by the nervous system.
the anterior pituitary gland produces LH but its target tissue is the gonads.

The circulatory system is responsible for transporting hormones from endocrine glands to target tissues.
