Antidiuretic Hormone (ADH), also known as vasopressin, is a hormone produced by the hypothalamus and stored in the pituitary gland that plays a crucial role in regulating water balance in the body. In the context of GCSE Biology, ADH helps to control the amount of water reabsorbed by the kidneys. When your body is dehydrated, ADH is released, causing the kidneys to reabsorb more water and produce more concentrated urine. When the body is well hydrated, less ADH is released, allowing the kidneys to produce more diluted urine. This hormone is essential for maintaining homeostasis, ensuring that the body’s fluid levels remain stable.
