WebThe kidneys play a central role in body homeostasis by adapting the renal excretion of fluid and electrolytes to bodily needs under the control of a systemic neurohumoral system. In addition to systemic control, primary intrarenal local regulation mechanisms are important for renal function and integrity. WebThe peritubular capillaries collect water and nutrients from the filtrate in the tubule. They also release substances that are secreted into the tubule to combine with the filtrate in the formation of urine. The capillaries ultimately merge into an interlobular vein, which transports blood away from the nephron region.
