Question: what is the function of antidiuretic hormone (adh)

title: Vasopressin
text: Vasopressin , also named antidiuretic hormone ( ADH ) , arginine vasopressin ( AVP ) or argipressin , is a hormone synthesized as a peptide prohormone in neurons in the hypothalamus , and is converted to AVP . It then travels down the axon of that cell , which terminates in the posterior pituitary , and is released from vesicles into the circulation in response to extracellular fluid hypertonicity ( hyperosmolality ) . AVP has two primary functions . First , it increases the amount of solute - free water reabsorbed back into the circulation from the filtrate in the kidney tubules of the nephrons . Second , AVP constricts arterioles , which increases peripheral vascular resistance and raises arterial blood pressure . 

Answer: answer: Vasopressin, also named antidiuretic hormone (ADH), arginine vasopressin (AVP) or argipressin. AVP has two primary functions: First, it increases the amount of solute - free water reabsorbed back into the circulation from the filtrate in the kidney tubules of the nephrons. Second, AVP constricts arterioles, which increases peripheral vascular resistance and raises arterial blood pressure.
answer: The antidiuretic hormones' two primary functions are increasing the amount of solute - free water reabsorbed back into the circulation from the filtrate in the kidney tubules of the nephrons, and constricting arterioles, which increases peripheral vascular resistance and raises arterial blood pressure.
