1 If the body is becoming fluid-deficient, this will be sensed by osmoreceptors, which results in increased secretion of ADH, causing fluid to be retained by the kidneys and urine output to be reduced.  The hormones ADH (Anti-diuretic Hormone, also known as vasopressin) and aldosterone play a major role in this.
Regulates Blood Volume The urinary system regulates blood volume by: 1) releasing renin, a hormone that after a series of reactions eventually restricts salt and water loss at the kidneys.2) adjusting the volume of water lost in the urine. 1  Regulates RBC Production.2  If oxygen levels in the blood are low, the kidneys release erythropoietin, a hormone that stimulates the hemocytoblasts (stem cells in the bone marrow) to increase red blood cell formation.egulates Blood Volume The urinary system regulates blood volume by: 1) releasing renin, a hormone that after a series of reactions eventually restricts salt and water loss at the kidneys.
