Module 13: endocrine system| page 1 of 13. Endocrine system consists of a series of glands that secrete different chemicals into the blood. These hormones travel throughout the body to their target site to initiate their effect. Functions of endocrine system: maintenance of internal environment (temperature, fluid volume, osmolality, adaptation to stress, control of growth and metabolism, control of reproduction. Actions of the endocrine system are slower to take effect but last longer and are generally ore widespread throughout the body (compared to the nervous system) Can indirectly affect many organs of the body at a distance by secreting chemicals into the blood (compared to the nervous system which has control over organs being in direct contact) Hormones divided into 3 basic categories: hormones derived from amino acid. Hormones are secreted into the blood in. Pulses by a very specific stimulus (neural or blood- borne) and in amounts that vary with the strength of the stimulus.
