Hormones are secreted by ductless glands, hence they enter directly into the blood stream which carries it to the targeted organ.
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.
