regulated by the osmolality of the circulating blood. Osmolality refers to the concentration of dissolved chemicals (such as sodium, potassium, and chloride; together called solute) circulating in the fluid base of the blood
ADH is a hormone produced in the hypothalamus and secreted by the posterior pituitary. ADH is secreted in response to decreasing blood volume. ADH affects the permeability of the nephrons in the kidney to water. ADH makes the nephrons more permeable to water, increasing the amount of water retained by the body. Homeostasis is maintained because more water is returned to the blood, decreasing the loss of water and maintaining the blood volume.
Water Balance
The principal cells in the distal convoluted tubule.
A. colloid osmotic pressure increases B. ADH production increases C. plasma osmolality decreases D. aldosterone production decreases Answer: When...(B) ADH production increases

Low concentration of water in body fluids suppresses ADH.

Kidneys (regulated by the pituitary gland released neurotransmitter ADH)

Antidiuretic hormone (ADH) is regulated by the pituitary gland. The anitidiuretic hormone maintains blood pressure and controls incoming water through the kidneys
adenohypophysis
hypothalmus
ADH
Endocrine
ADH controls the rate that filtrate moves from the glomerulus into Bowman's capsule. ADH is also the only hormone that provides a system of control over the kidneys as an osmoregulator for urine production. Low levels of ADH in the blood are the brains response to thirst. Also during times of higher solute concentrations, ADH causes more water to be realesed from the nephrons to be reabsorbed by the blood.
