Hormones are the chemicals which are produced by glands. By definition they pour there secretion/secretions in blood. Blood carry the secretion through circulation to target organ/ organs for desired effect. Usually target organ sends back the message to reduce the secretion of the hormone producing gland. This is called as negative feed back effect. (Like thyroid stimulating orAdrenocorticotrophic hormone by anterior pituitary gland.) Sometimes hormone like Follicle stimulating hormone stimulates ovarian follicle. Which in turn produces hormone estrogen. Main female hormone. Thyroid hormones increase the 'basal metabolic rate' of body.
