Feedback:
Many hormones are secreted in the hypothalamus, which in turn control the release of hormones by the pituitary gland. Endocrine glands secrete hormones that are transported to target tissues through the circulatory system and directly into the blood stream. The parathyroid regulates the amount of calcium and phosphorus in the blood. The adrenal medulla secretes hormones that mimic the action of the sympathetic nervous system.
