Osmoreceptors are capable of detecting water concentration and are
located on the hypothalamus next to the circulatory system. The
hypothalamus (part of the brain) sends chemical messages to the pituitary
gland next to it. The pituitary gland secretes anti-diuretic hormone (ADH),
which targets the kidney responsible for maintaining water levels. When
the hormone reaches the kidney, it alters the tubules of the kidney to
become more / less permeable to water. If more water is required in the
blood stream, high concentrations of ADH make the tubules more
permeable. If less water is required in the blood stream, low concentrations
of ADH make the tubules less permeable is this
