Yes, all hormones are released into the blood stream and then circulate to all tissues; only those target tissues that are designed to react to specific hormones will react to the presence of the hormone. Hormones are chemical messengers that are released into the blood stream, designed to cause changes in only certain tissues.
Endocrine glands, such as the thyroid gland, adrenal glands, and pituitary gland, are major tissues that synthesize hormones in the body. These glands are specialized to produce and release hormones into the bloodstream to regulate various physiological functions.
Most hormones are made of protein called peptides. Peptides are short chains of amino acids serving as a major form of communication between different organs and tissues. Hormones help to regulate a number of our body's activities such as digestion, sleep, stress, growth etc.
The major tissues involved in the skeletal system include connective tissues and muscle. The connective tissues help hold the skeletal system together.
Hormones travel from endocrine glands through the bloodstream to reach target organs or tissues where they exert their specific effects. Some of the major endocrine glands that release hormones into the bloodstream include the pituitary gland, thyroid gland, adrenal glands, pancreas, and ovaries/testes.

The three major effectors of the nervous system are muscles, glands, and other neurons. Muscles respond to neural signals by contracting or relaxing, while glands secrete hormones in response to neural input. Neurons can also act as effectors by transmitting signals to other neurons or tissues.
