Hormones are chemical messengers secreted by endocrine
glands
They transported to the target cells in the bloodstream.
Hormones produced by cells in one part of the body can
affect cells in another part of the body.
Each target cell contains receptor proteins; it receives and
responds to the chemical message sent by the hormone.
Hormones regulate various human functions, including
metabolism, body’s growth and development, tissue function,
emotion, and sexual development and function

provides integration and control of the organs and
tissues.
The endocrine glands are the pituitary, pineal, thyroid,
parathyroid, and adrenal glands
The tissues and organs that secrete hormones are the
hypothalamus, thymus, pancreas, testes (male), and
ovaries (female).
