Regulation

The function of the urinary system is regulated by various hormone axes within the body.

In this section we shall consider the role of antidiuretic hormone (ADH), also known as vasopressin. It is a small peptide hormone that is responsible for regulating the body’s retention of water and is one of only two hormones secreted by the posterior pituitary gland.

We will then look at the Renin-Angiotensin-Aldosterone-System (RAAS). This is the hormone system within the body that is responsible for the regulation of blood pressure and fluid balance.The system is mainly comprised of the three hormones renin, angiotensin II and aldosterone. It is mainly regulated by the rate of renal blood flow.
