Final answer:
Antidiuretic hormone and aldosterone are the hormones involved in the regulation of urine volume. Antidiuretic hormone acts on the collecting ducts to increase water reabsorption and decrease urine volume, while aldosterone promotes sodium and water reabsorption.
Step-by-step explanation:
The hormones involved in the regulation of urine volume are antidiuretic hormone and aldosterone. Antidiuretic hormone (ADH), also known as vasopressin, is produced in the hypothalamus and released by the posterior pituitary gland. It acts on the collecting ducts in the kidneys to increase water reabsorption and decrease urine volume. Aldosterone, which is produced by the adrenal glands, regulates sodium and water balance in the body. It promotes the reabsorption of sodium, leading to increased water reabsorption and decreased urine volume.
