Detailed explanation-1: -Water levels in the body are controlled by antidiuretic hormone (ADH), which is produced in the hypothalamus and triggers the reabsorption of water by the kidneys. Underproduction of ADH can cause diabetes insipidus.

Detailed explanation-2: -Antidiuretic hormone (ADH) is clearly the hormone of paramount importance in the regulation of water excretion by the mammalian kidney. However, other hormones also influence renal water excretion and this portion of the symposium will examine how some of these hormones exert their effects.

Detailed explanation-3: -ADH primarily affects the ability of the kidney to reabsorb water; when present, ADH induces expression of water transport proteins in the late distal tubule and collecting duct to increase water reabsorption. Several disease states arise when the body loses control of ADH secretion or responds to its presence.

Detailed explanation-4: -ADH is produced by the hypothalamus in the brain and stored in the posterior pituitary gland at the base of the brain. ADH is normally released by the pituitary in response to sensors that detect an increase in blood osmolality (number of dissolved particles in the blood) or decrease in blood volume.

Detailed explanation-5: -ADH is a substance produced naturally in an area of the brain called the hypothalamus. It is then released by the pituitary gland at the base of the brain.
