Detailed explanation-1: -More ADH will be released, which results in water being reabsorbed and a more concentrated but smaller volume of urine will be produced. This type of control is an example of the negative feedback mechanism. It aims to keep the concentration of the blood plasma constant.
Detailed explanation-2: -ADH Controls Distal Nephron Permeability. ADH increases the water permeability of the late distal tubule (or connecting duct) and all parts of the collecting duct. It also increases the urea permeability of the inner medullary collecting duct.
Detailed explanation-3: -Antidiuretic hormone (ADH) has the primary role in osmoregulation by controlling the amount of urine formation. Body maintain water and electrolytes concentration at a relatively constant level by the mechanism of osmoregulation. Hormone are important signaling molecules that control the regulatory process.
Detailed explanation-4: -Water excretion by the kidney is regulated by the peptide hormone vasopressin. Vasopressin increases the water permeability of the renal collecting duct cells, allowing more water to be reabsorbed from collecting duct urine to blood.
