Antidiuretic Hormone - The Body's Water Regulator

Antidiuretic hormone, which is also known as vasopressin, is a hormone secreted from the posterior pituitary that acts on the distal nephron to conserve aqua and regulate the tonicity of body fluids. Aqua deprivation provides both an osmotic and a volume stimulus for ADH release by increasing plasma osmolality and decreasing plasma volume. Aqua administration lowers plasma osmolality and expands blood volume, inhibiting the release of ADH by the osmoreceptor and the atrial volume receptor mechanisms. More information: click here
