The kidneys receive 25% of the cardiac output. From this they filter 20% of the plasma forming a filtrate of which all but 1% is reabsorbed. This equates to all the circulatory volume being filtered and reabsorbed every 30 minutes. The kidneys respond dynamically to changes in blood pressure and hydrations status, using several mechanisms of regulation including the [[Important Hormonal Regulators of the Kidney - Anatomy & Physiology#The Renin Angiotensin Aldosterone System (RAAS)| Renin-Angiotensin-Aldosterone system]] which can alter the movement of sodium chloride and water in the vascular system and extracellular spaces.

The kidneys are responsible for the production and release of two [[The Endocrine Function of the Kidney - Anatomy & Physiology|hormones]]- Erythropoietin and Renin, which are produced in the Juxtaglomerular Cells. The kidneys also regulate the activation of vitamin D.
