How does Adh promote urine concentration?

ADH:

1. Human vasopressin is a hormone that is produced from the AVP gene as a peptide prohormone in neurons in the brain and is converted to AVP.
2. It is also known as the antidiuretic hormone, arginine vasopressin, or argipressin.
3. AVP serves two main purposes.
4. The first benefit is that it increases the volume of solute-free water that is reabsorbed into the bloodstream from the filtrate in the nephrons' renal tubules.
5. Second, AVP narrows the arterioles, which raises arterial blood pressure and peripheral vascular resistance.
6. The brain releases a substance called antidiuretic hormone (ADH), which makes the kidneys release less water and reduces the volume of urine generated.
7. The body makes less pee when its ADH level is high.
8. A low level causes more urine to be produced.
