ADH, or antidiuretic hormone, is a crucial hormone that plays a vital role in maintaining the water balance within the body. Produced by the hypothalamus and released by the posterior pituitary gland, ADH works to regulate the amount of water excreted in urine. This is achieved by increasing water reabsorption in the kidneys, resulting in a concentrated urine and conservation of water. ADH release is carefully controlled by factors such as blood osmolarity and volume, ensuring that the body maintains a proper balance of fluids. Its key role in conserving water makes ADH an essential hormone in situations where the body needs to preserve fluid, such as during dehydration.
