One of the ways the hypothalamus does this involves controlling the pituitary gland. The hypothalamus does this by using its own hormones to communicate with the pituitary.
Among the things monitored by the hypothalamus is the level of various hormones in the blood. The hypothalamus has special cells which receive information from the body indicating how much of each hormone is present in the bloodstream. When these hormones drop below a particular level this stimulates the hypothalamus to release hormones. These hormones travel to the pituitary gland, acting as the signal to the pituitary to produce one or more of its hormones. The hormones produced by the pituitary are released into the bloodstream. The bloodstream transports the pituitary hormones to other endocrine
